The Core i5-8600K is one of Intel's mid-range Desktop processors. It was released in 2017 with 6 cores and 6 threads. With base clock at 3.6GHz, max speed at 4.3GHz, and a 95W power rating. The Core i5-8600K is based on the Coffee Lake 14nm family and is part of the Core i5 series.

Core i5-8600K is also the successor of Intel's last gen Core i5-7600K processor that was based on the Kaby Lake-S and 14nm process and was released in 2017.

In our mind, the best processors are the ones that deliver outstanding performance at a reasonable price point. And, the Core i5-8600K absolutely nails this concept.

Unfortunately, this doesn’t quite translate to as strong of a single-core performance, even if Intel is closer than it’s ever been to matching AMD core for core. In our single-core GeekBench and Cinebench tests, the Core i5-8600K scored a 4561 and 183, respectively. This is definitely a huge leap over the Core i5-7600K, but it’s slower than the Ryzen 5 2600X, which scored a 4823 and 176 in the same tests. But, that’s still not a huge difference, so the multi-core gains generally outweigh them.

That something is the Core i5-8600K. Intel cranks the TDP dial up to 95W on this 6-core 6-thread chip, making it the high-performance counterpart to the 65W Core i5-8500, which is basically the same 14nm chip built with the Coffee Lake microarchitecture, but with a lower TDP rating. That chip came away from our first look at the Coffee Lake series with an Editor's Choice award, going toe-to-toe with AMD's Ryzen 5 2600X, so it's fair to say we have high hopes for the higher-performance model. Intel still hasn't sampled the chip to the press, so we bought one at retail to put it under the microscope.

But we've also found that, after simple push-button overclocking, the Core i5-8500 offers similar performance to the Core i5-8600K, even when it is also overclocked. But for $70 less. The Core i5-8600K is an impressive chip and offers a better mixture of performance than AMD's Ryzen 5 2400G, no doubt, but in this case, value seekers might opt for its less expensive sibling.

As the higher-priced version of the Core i5-8500, the Core i5-8600K has higher base and Boost frequencies of 3.6 and 4.3 GHz, respectively. That's an increase in base frequency and a bump to boost clocks, but the real advantage should lay in the higher Package Power Tracking (PPT) envelope, which is a measurement of the maximum amount of power delivered to the socket. The Core i5-8500's PPT tops out at 65W, while the motherboard can pump up to 142W to the Core i5-8600K at peak performance. That opens up much more aggressive boost behavior, on both single and multiple cores, that could widen the performance gap beyond what we see on the spec sheet.

The Intel Core i5-8600K was rolled out on Oct 2017 for $257, which puts it in the same general price range as the last-generation Core i5-7600K. This means that at least we're not seeing any considerable price jumps from generation to generation.

The Intel Core i5-8600K is another impressive release from Intel and its 8 Generation of Core i5 chips. With it, you’re getting 6-cores and 6-threads, with a boost clock of 4.3GHz. It may not be the strongest contender ever made on paper, but when you see and feel the actual performance gains it offers, you’re certainly getting a lot of bang for your $257 buck.

Bear in mind, however, that if you already have something like the Core i5-7600K, this generation doesn't offer the biggest boost in performance. You might want to wait another year or so before dropping a few hundred bucks, or even opt to splurge on a higher-end but pricier chip.

So which should you buy? Let's get that out of the way. Before this comparison review we updated our Best CPU feature and we said you should go with the Ryzen 5 2600X as it comes with a better stock cooler, can be overclocked, and the AM4 platform offers a significantly better upgrade path.

For general computing the Ryzen 5 2600X can take advantage of multi-threading capabilities and will be considerably faster than the Core i5-8600K on heavy application workloads. Remember the Core i5-8600K is only marginally faster than the Core i5-7600K, so you can safely use the older model as a measuring stick. For rendering and encoding workloads the Ryzen 5 2600X can up to 33% faster.

Moving beyond games, it’s an easy win for the Ryzen 5 2600X. The Ryzen 5 upgrade path on A320, B350, B450, X370, X470, X570 motherboards, all support upcoming Zen+ processors. So if you buy a nice A320, B350, B450, X370, X470, X570 board now with the Ryzen 5 2600X, you’ll be able to slap a Coffee Lake processor on there later in the year, or whenever you deem it necessary.

For a 6-core processor, Intel’s $257 flagship Core i5-8600K processor seems downright cheap. On paper, the cost of those 0 extra cores is almost an afterthought when you stack it up against its direct competitor, the $229 6-core AMD Ryzen 5 2600X.

If extended overclocking and boost frequencies are trivial matters to you, Intel also offers the Core i5-8500 at $202. It’s still outfitted with 6-cores and 6-threads, but clocks in at a slower 3GHz and maxes out at only 4.1GHz.

Now the biggest question is can Intel’s Core i5 processor play games? The answer is simply yes as it got a respectable gaming score of 93% in our benchmarks.

Fresh from a successful roll-out of mainstream Core i5 CPUs, Intel's attack on AMD now extends down into the mid-range with its Core i5-8600K processors, which the company is making available as of Oct 2017.

Upgrade Help: Looking to upgrade my 8600k to a Ryzen chip at the end of the year

I'm considering the higher end 3000 series Ryzen CPUs ( 3700x primarily ) since they'll likely be dropping further in price after the 4000 series hits the market in a few months and I'll have to shell out for a new mobo as well.

Primary use case is high resolution gaming - 1080ti and 3440x1440 120hz monitor. Trying to eek out every last frame from the CPU, if possible.

Secondary use case is creative work in InDesign, Photoshop, Illustrator , and occasionally Premier . I'd like to say it'll be used for Blender or Solidworks as well, but my education in those programs is kind of on-hold at the moment.

I'm aware that in terms of raw gaming performance, typically Intel is on top, as most games are single core or single thread dependent, but I can only seem to find benchmarks that focus on 1080p gaming, rather than UWQHD or even 1440p in most cases, so

(A) I'm not sure how those chips stack up at higher resolutions and (B) I've been looking to make the move to Ryzen for awhile and their chips are largely competitive with Intel at this point.

I initially considered the 3900x , but that chip gets little to no benefit in gaming scenarios over the 3700x and costs substantially more. My workload tasks are not substantially taxing enough to warrant the extra cost. I also looked at the 3600 , which is a competent gaming chip, but seems like more of a sidegrade (admittedly, with added threadcount). I know there are 'tweener skus (the 3800x and the 3600x ), but the price to performance ratio on those seems unjustifiable as well.

TL:DR - Which CPUs should I be considering for purchase near the end of the year for a high end gaming rig that I use secondarily for creative work? Is the 3700x a good choice, or should I be looking ahead to next generation's 4600 chip?

MoChuang July 16, 2020

As of right now it sound likes the 3700X is the way to go. But I’d keep an eye out for the 4600 benchmarks. It might be better for you.

2060 gpu and a i5-8600k usage problem. Please help

Hey, I need big help. So basically, I have a rtx 2060 graphics card, an i5-8600k processor and 8g of ram. My problem is that my usage for the cpu is at 100 on most games, but the usage on my gpu was like 30% on the dot. I don't understand why because this shouldn't be a bottleneck. I've been having this problem ever since I got the graphics card. If anybody can help me that would be so great because when I was getting this gpu, I was so excited just to find out that my pc is under performing. I hope I can get help. Thank you.

I don't really know. I was playing fortnite on like all low settings, my cpu was at 100%, gpu at 30% and my ram was around 60% to 70% and then on gta the only thing that was different was that my gpu was on 55% - 65%

P
poqbassc July 14, 2020

first of all u need to confirm bottle necking by comparing ur fps or benchmarks online (shadow of the tomb raider benchmark or uni engine heaven benchmark) if the fps checks out dont worry. but 100% load on cpu and low load on gpu is indicative of bottlenecking but u havent given any context so do this:

benchmark using shadow of the tomb raider or uni engine benchmark if u dont have SOT.

U play at which resolution and what kind of gaming you do? ( high refresh rate , titles u play etc)

Do u run any kind of background processes while gaming?

The rest of your specs.

P.S Tht combo should not bottleneck

C
CJEric31005 July 11, 2020

well I don't know too much about pcs but ill try to share as much info as possible. I play at 1920 x 1080 res, I'm usually on discord while im playing, and thats it, I play fortnite, gta, csgo, valorant, minecraft, and thats pretty much it. My max refresh rate is 144hz, and could you tell me which specs you want me to say and ill tell you. Thanks for the help, i really appreciate it.

Overclocking i5 8600k problems and help please?

Hi all,

I was overclocking my CPU yesterday and I was struggling to get stability when testing. I’ve got my chip at 4.8Ghz 1.33V as when I put it to 5ghz at 1.36 it still was blue screening and I didn’t want temps to go too high so I dialed back the clock speed. Now my question is when stressing with prime 95 after about 5 mins or so clock speed drops to 3.8ghz-4ghz but the stress still runs and all. Temps are sitting below 80C max after about 15 mins of testing. Hovering mid 75C most of the time.

Does this mean it’s still unstable?

What should I do to try get that 4.8GHz constant?

Or should I drop clockspeed

T
Tenacious_Dani July 14, 2020

It really depends on the specific chip you got in the silicon lottery, to be honest I keep mine at a boring 4.7 at 1.285 stable and reasonably cold, and in happy with that.

H
Helpme994 July 11, 2020

Does the drop in GHz when stress testing mean it’s not stable though?

Help to i5-8600k @ 5ghz? :)

Hey! For the last days I've been using the quarantine to overclock my 8600k that I own for almost two years now! I am here asking for your guys opinion since right now, I'm running at 4.9ghz 1.285cv and it works like a charm. Now, I got it to work at 5.0ghz @ 1.355cv and in gaming sessions it worked fine but in prime 95 i got some super high temperatures, around 95°C. What is your opinion? Should I stick with the higher voltage for 0,1ghz or just run it lower? I also think prime95 is very unrealistic as aida64 at 5.0ghz @ 1.355cv ran fine under 70°C. I'm already happy with the 4.9 but I guess this is what overclocking is: push every tiny bit of performance... I am also using LLC4 in my msi motherboard.

Specs:

I5-8600k

MSI Z370 Tomahawk

Seasonic Focus GX850

Rtx 2070 super

Trident z rgb 3200 cl16

ML360R RGB

Thanks!

arichardsen May 14, 2020

I'd much rather have 4,9 at the lower voltage. The increase in voltage to high to only gain 0,1ghz IMO.

P
Powiii May 29, 2020

Yeah, in real workloads I don't know if I would notice the impact of 0.1ghz...

B
BrendanHayes May 14, 2020

If you’re willing, delid the CPU and put some LM in there. Should help temps considerably and you won’t have to worry about choosing between the lower or higher voltage

P
Powiii June 01, 2020

Yeah... I've been thinking about this, but I guess this is the next level

J
jaycruzer17 May 11, 2020

I was able to get 5ghz at 1.315v but tbh it doesn’t matter lol. Go with the 4.9, safe some electricity :)

G
Gsonz May 26, 2020

I would stay at 5GHz as long as your temps are acceptable while gaming. Prime95 is a pretty unrealistic workload, you shouldn't care about the temps too much while running this. Just make sure your CPU isn't throttling while running prime95, otherwise you wouldn't test the CPU's stability at full clock speed.

5GHz is pretty rare for an 8600K, congrats for reaching this speed and keeping stable :)

P
Powiii May 14, 2020

Is it really that rare? I thought it was a very common speed for this cpu. Alright, I'll check for throttling then!

I5 8600k second hand for 650 euros or build new? Help!

Hi guys I need some help. I'm looking to upgrade my i5 760 @4ghz. Do you think this is a good build for the price and relatively future proof with a possible 9900k upgrade path in the future (also second hand when prices drop). I currently game on 1080p but would like to upgrade to 1440p in the near future. I can get this build for 650 euro and sell my own, or I could reuse some of my old build and upgrade ram/motherboard/CPU and maybe psu.

Second hand build: GPU: Gigabyte GTX1070 8GB GDDR5 CPU: Intel I5 8600K RAM: 16GB Corsair Vengeance LPX DDR4 Motherboard: ASRock Z370M-ITX Geheugen: 512GB SSD, 2TB HDD Cooler: Noctula Psu: Seasonic FOCUS Plus Series 550W Case: Cooler Master Elite 130

Or is it better to build a new PC with a Ryzen 5 3600 for example and keep the GPU and SSD and shitty case of my current build. If not I would sell it.

My current build is: I5 760 @4ghz P7p55d deluxe 16gb ddr3 ram Gtx 1060 6gb 500gb ssd 860 evo 750 watt psu

I think it's worth around 300 euros? So if I would take the secondhand and sell mine I would pay approximately 350 euros for an immense CPU upgrade, extra storage, better GPU and ram. Though I'm not sure if it's a wise upgrade looking for the coming years. As you can see by my build I don't upgrade a whole lot haha. Would love to hear your opinions! Thanks in advance.

Limpis12 June 10, 2020

tbh going from a i57600 to a 8700k is not a "immense" upgrade. SAme with a 1060 to a 1070. I would personally not bother and just try to sell and build a new. Possible save some parts idk. But if i would go from a 1060 i would atleast go for a 2060 super/5700xt. IF saving money for a couple of months is an option i would highly suggest it even tho you wouldnt pay that much.

P
Poebes June 16, 2020

Thanks for the advice! It's a i5 760 though, not a 7600. So it's very old.

Critics Reviews

Core i5-8600K's unlocked multiplier fits well with the Z-series boards, which are needed in order to manipulate its ratio. Intel also added a few new overclocking knobs and dials, such as per-core ...
The Core i5-8600K is still a great CPU if you can find one on the cheap, but for those looking for the absolute best gaming CPU around the £250 / $250 mark, the i5-9600K should definitely be at the top of your list.
Intel's Core i5-8600K is priced $120 below the i7-8700K, making it an interesting option for the more value-oriented buyer. It features the same six-core design, but lacks HyperThreading and loses 3 MB of cache. Our testing shows that it still is a great CPU, especially when overclocked to almost 5 GHz.
The Intel Core i5 8600k overclocked, benchmarks and built on a Z370 Gigabyte Aorus Gaming 7, 16 GB of Team Group RGB Ram, M.2 and a good ol' 980 ti. Perfect gaming system in 2018. Thanks for ...

PC didn't switch on,
After doing the yearly cleanup PC didn't switch on, rooted the problem to the cpu. Took PC apart, cpu seems suspicious. All parts approx 2 years old, no overclock, cpu - i5 8600k. Image here - https://ibb.co/41wrndQ

The 4 pads immediately to the left of center are definitely burned. Some serious arcing occurred there. Check the corresponding pins in the socket and you'll likely see damage there as well. You can try to clean this but it's likely a writeoff for both.

Gigabyte RTX 2080 TI Fans Ramping Up and Down
Hello,

Recently my Gigabyte Aorus RTX 2080 Ti Xtreme 11G graphics card has been experiencing an issue where the fans will ramp (while gaming) up to 4000+ RPM as the GPU temperature reaches 85c degrees and then as the GPU drops to 84c degrees, the fans instantly drop to ~2000 RPM. As such, the fans go into this endless cycle of up, down, up, down. With that an increase in extreme noise.

Seen here ( View: https://imgur.com/a/hQUkqio
) in the software, you can see what is happening along with the GPU's current settings for power. The fans are in this up, down cycle while the GPU temperature remains essentially constant and, as expected, so should the fan. I've attempted to clean reinstall the Aorus software in case it was a bug in the Auto fan curve, but the problem remains. Further troubleshooting included setting the fan speed to a Manual setting of 100% and creating a custom fan curve, but each time the GPU ramps the fans to 4000+ RPM the moment it hits 85c degrees. Regardless of the setting. The problem continues on stock settings as well.

The case is properly cooled in a Corsair Crystal 680X case with three LL120 intake fans in the front, two at the top acting as exhaust, one in the rear also acting as exhaust, and finally two Noctua fans positioned at the bottom; again, acting as exhaust. All are 120mm. The rear compartment is cooled by a Noctua slim 92mm fan. The graphics card sits vertically in the case.

My problem was first discovered a few weeks ago, but no major system changes were made then. In attempt to help resolve the issue and rule out the Aorus software having a bug, a full clean reinstall of Windows 10 was performed a week ago. The software has been reinstalled.

Other specifications of the system include a Gigabyte Aorus Gaming 5 motherboard, i5-8600K CPU, 16GB 2666MHz RAM, and a 750W Platinum SeaSonic PSU.

This problem just recently started to happen and I am not sure what caused it. Any assistance or thoughts on what to help here would be appreciated.

Yeah, do it when you have time. The reason being:

Upgrade from i5 8400 to 8600k?
Okay so I am going to upgrade my gpu from a gtx 1060 3gb to an EVGA rtx 2060 KO. I currently have an i5 8400 and I want to know if it will bottleneck. If so, should I upgrade to the 9600k?

Not worth it. It's same 6core/6thread cpu, just with slightly higher clocks.
Consider upgrading to i7 instead - either i7-8700 or i7-9700.

No signal suddenly, loses signal intermittently
TLDR: No signal on boot but win7 boots up normally. If boots with display, loses signal randomly with 'display driver blabla has crashed and successfully recovered.' in event log. Do read the whole story below

Long diary/backstory:
Spoiler: Detailed happenings Hi, my pc has been working fine for 2 years but on 24th mar 2020, booted my pc with no signal. Fans running, booted to desktop(can hear the music) but monitor no signal. Let me label this as ' disease 1'.

Few days later after trying many things, it suddenly can display signal. However, while I was playing path of exile my display crashed and no signal: . My game crashed but my windows music player is still playing while my display has no signal and pc fans spin like crazy: Disease 2. Pc unable to display signal on boot again: Disease 1. After trying many things for 5 mins it was still futile. 55 mins later, pc able to boot again with signal.

Checked window event logs, noticed ' display driver (nkdvm or something) has stopped responding and has successfully recovered.'

DDU uninstall my current gpu driver, installed latest driver but disease 2 still persists intermittently over the next few days.

once, System was also free of disease 1 and 2 for about a week.

When disease 2 happens which leads to disease 1(no signal on boot), seems to be healthy if i wait for about an hour before booting.

Sometimes it display no signal while booting up, sometimes it happens few sec after the desktop appears. Few times it happens while i only have the browser on.

But from last week onwards, been stuck with disease 1. List of things that i tried:
Reseat ram, boot w/ 1 ram, change ram slot, brushed contacts
Clear cmos, tried booting without cmos(cmos not smooth and shiny)
Reseat gpu, brushed contacts.
Reseat cpu, thermal paste still wet. No visual prob
Uninstalled and updated gpu driver
Took out mobo, carefully cleaned it with a brush ( wasn't very dusty)
Onboard graphics didnt work
Tried 3 diff hdmi, 1x dvi d dual link cable
Tried unplugging monitor power cable while connected to the wall socket and holding the monitor power button for 1min
Breadboard mobo with 1 ram,cpu and cpu fan, psu (pc case pretty old so i tried this)
Tried holding onto pc power button for a min
Tested psu with multimeter while not under load: all within approved volts


Things that I haven't tried:
Diff monitor
Diff gpu( doesnt work with onboard though)
Diff mobo/cpu
Diff psu

Sys spec

Psu. Corsair mwe 550w gold

Gpu. palit geforce Gtx 1070

Mobo. Gigabyte z370p d3 rev 1

Cpu. Intel Core i5-8600K 3.6 GHz 6-Core Processor

Ssd1. 1tb samsung 860 evo
Ssd2. 250gb samsung 850 evo

Ram. Ddr 4 2x 8gb 2933mhz corsair vengeance lpx

Monitor. Acer GN246HL 24.0" 1920x1080 144 Hz Monitor

Os: win7

Date of built. Around 2018 october, ram and monitor upgraded from 2019 onwards.

Possible cause:
2018 oct, during installation of cpu, circuit breaker tripped (pc was plugged but off for me to touch the metal case to discharge wateva static electricity i have)

Sometime around 2018-2019, conventional oven tripped my circuit breaker while pc on

Early march 2020, lightning strike my hdb flat and tripped my circuit breaker while i was using my pc. (I heard lightning strike may damage the pc component but effect is not instantaneous)

Random knocks onto pc case during the 2 years( pc desktop case on the floor, knocks are rare and not powerful)

Pls help and suggest any solution

Should i buy a new mobo,psu or even cpu? Cant really tell which one is the problem
If i were to buy a new mobo and psu but the culprit is cpu, will the cpu damage my mobo/psu? I heard the probability of dmg is very slim but i would like to double confirm

Will a corrupted system cause this? Im unable to get signal even when breadboarded without ssd connected

But with igp it displays fine? Then likely that the gpu got problems too. Can look at how the next guy cleans pcparts. Maybe cleaning the gpu like that will help, but have litle hope if it was really a shock that made it die.

Is this worth it 1080ti with i7 8700k for 1000?
Good morning,
Just putting a feeler out there to get some opinions on if I should buy this PC off someone or just build my own and spend a little more with newer tech given there are newer things coming out. I play a lot of games in 4k currently on a 1070ti with an I5-8600k. The link below is the parts that they listed were in there to the best of my ability.

It is NOT a $2500 build new. The GPU and CPU are vastly overpriced on the PC Part Picker list because hardly anybody is selling them new anymore. Those are "ooh, hey, look, I have a rare, hard to find item" price, and I would be VERY surprised if those weren't 3rd party sellers.

The launch price of the i7-8700K was $359. 2 years ago, that video card was under $800 new. That doesn't count the fact that the 5700XT which matches its performance, and the 2070 Super, 2080, and 2080 Super all outperform it, and are all available within the $400-$800 range.


A used PC comes with no warranty. The best way to tell if this is worth it, is to see if you can put together something with current generation components, but that performs about the same, for less, for the same price, or even for a little more. That little more would still be worth it because everything is new with warranty, rather than used.

Evga 550 watt power supply (new)
And i had a Rx 470 msi gaming x 4gb from my last build
The case is corsair 275R gaming with 3 fans
When ever i play a game the pc shutdowns down and the gpu temps reach 90C+ ,
What can i do

Probably needs to have the cooler removed, thermal pasted removed and re-applied from the GPU.

Additionally you can reduce power by manual voltage tuning.

My MSI RX480 Gaming X is running [email protected] right now at a slightly reduced 1235MHz and pulling 85W. 66C @ 17% fans.

Adding Ram to motherboard
So as my title says I'm looking to add ram to my motherboard. I'm not to knowledgeable on adding and I cant find a clear answer as to whether or not it's ok to add ram. Only information I did find was when upgrading you want to get a new motherboard. I'm not upgrading or rather I dont need to, I plan to use the existing 2 4gb sticks I have and add 2 more of the same kind. So I'm unsure if I can just add the 2 and itll be fine or if I need a new motherboard to add more.

If you need it my motherboard is a MSI Z307 gaming plus and my cpu is an i5-8600k.

If you get a 16 GB set with the correct specs for your current MB of course you can use them with your current MB.
That would be the most ideal case.
However I think there is a good chance two sticks with matching specs to your current specs will work. Most of the time I do this it works.

My computer won’t boot when my cooler is attached
Computer won’t boot with cpu cooler on... So this started one night I was playing rocket league and my computer just shut off, then I turned it back on and no post. I trued a couple times still nothing. I figured it might be the power supply bugged out so I bought a new one... not the proble, I then reset the cmos, still nothing. But I have been ignoring the cpu light that shows up when there is a problem with the cpu(i5 8600k)so I took the cooler off ( cooler master 212 evo) and reseated the cpu and re applied thermal paste tried booting without the cooler on first and it worked! There was a post, problem solved right? No.... then I put the cooler back on thinking everything was good, no post. Took cooler off it posted again. The computer only boots with no cooler on the cpu. I’ve never heard of this any ideas?

Computer takes a long time on post screen before booting or loading the BIOS
Hi,
I recently began having issues with my computer startup. I have to wait 1 min+ between the time that the Post screen appears (Asus ROG, press del or f2...) and when the computer either enters the BIOS (when I want to go into the BIOS) or boots to windows. Any suggestions or further troubleshooting ideas would be greatly appreciated.

Background:
A couple days ago I started having issues with windows startup, and after a bunch of troubleshooting and attempts to restore Windows 10 boot, I ended up reinstalling Windows. I may have thought that the issue I am having currently was an issue with Windows, and if so, this problem began randomly after a routine restart. Before this issue my PC went from power button press to windows login in about 5-10 secs.

Info:
  • My boot drive is first in the boot priorities.
  • I have checked all of the connections inside my desktop.
  • Specs:
    • Intel i5 8600k @4.6GHz
    • ROG STRIX Z370-I Gaming
      • BIOS Version: American Megatrends Inc. 1002 (7/2/2018)
      • SMBIOS Version: 3.0
    • MSI Duke GTX 1080
    • 16GB Team Vulcan RAM
    • Kingston SA400S37 120G (Boot drive)
    • ST3000DM001-1CH166 (2TB secondary drive)
Thanks All!

Hi,

I'd be more than happy to try and help you figure this out some more. So, does your motherboard by chance have any digital codes when it is initially POSTing? They would either be on the motherboard physically, or on the ASUS splash screen in a bottom corner probably. If so, look to see if there is a code that is taking a while to get past during the 1+ minute standby period. If you see it getting hung up on a specific POST step, you can look in your motherboard's manual to see what the code means.

Secondly, you could try to remove every single HDD/SSD except the boot drive and see if that helps the boot time at all.

Let me know if you have any success. Hope this helps

Windows 10 not booting, goes to "Preparing Automatic Repair"
Hi all, I'm having the above issue. After fitting some new fans (Silent wings) and connecting a new monitor (Dell), I went to start up my desktop only to get the "Preparing automatic repair" screen which shortly leads to the blue screen wth "Your PC did not start correctly."

In the bios, my hard drive is still visible under SATA information. I checked the connectors to the hard drive to make sure it wasn't as simple as that. CPU temperature is fine. My intital thought was that the motherboard couldn't handle the new fans and this somehow caused an electrical fault. The fans are: two PWM 120mm fans connected to CPU header via a splitter (0.37A each), one 3 pin 120mm case fan (0.12A), one 3 pin 140mm case fan (0.5A). However, am I right in saying headers should manage up to 1A without issue?

At one point, the PC did turn off on its own, this was prior to getting those dreaded screens first appearing. I'm not sure if the turning off was an electrical/fan issue or if the PSU simply came loose at one point, but thought I should mention it.

I performed a windows 10 update several days ago, without any issue at the time.

Right now, I'm able to reach Advanced options, however I'm unsure how to proceed. My options include doing a system restore point or booting up from a system image back up. The system restore option is giving me the choice of rolling back to a point 2 days prior to this happening. As for system image backup, I have a recent back up made on an external drive and repair disc.

What is the correct way to proceed? I was really tempted to go for the first option, having a point only 2 days ago seems ideal but held back as I've no idea if this will screw me over! Any help is really appreciated.

Current build:

Asus TUF H370 pro board
i5-8600k cpu
16GB DDR4 RAM
Asus R9-290x graphics card
Neptune 240 cooler
Corsair TX650 psu

The cpu is not overclocked, it was chosen over the regular version because it was actually cheaper.

onespeedbiker April 13, 2019
I'm still thinking about you simply adding/ upgrading some case fans and suddenly your PC won't boot. Assuming everything was running fine before the new fans, it doesn't seem logical that you hdd is now going bad. You also said you plugged in a new monitor. Did you also get a new/different graphics card? Even if not, if you are using a plug in discrete graphics card, you might want to reseat the card, as you might have loosened it changing monitors.

Not sure what component(s) to upgrade
Hi,

I mainly play VR games, Racing sims and FPS games and im looking to upgrade my rig (mainly for my Valve Index performance). I game on 1440p 144hz and on my Valve index VR headset.

my rig:
-i5 8600k @4.8Ghz
-RTX 2070S
-2x 8GB Gskill Ripjaws V Ram
-ASrock Z370 Extreme 4

My GPU is the lowest priority in terms of upgrading, but I'd love to hear your thoughts on what could improve my gaming performance!

PC doesn't turn on unless I switch PSU back and forth few times
So recently my PC doesn't want to turn on after pressing power button, no moving fans absolute silence. I haven't switched any components recently, checked the motherboard and I can't see nor feel any swollen parts.
Also checked frontpanel and other basic stuff. After I manage to turn it on it works like usual.

and its modular
