Hi guys,

Need your help with a question. I built a new PC a couple of weeks ago, it's been working well, except that sometimes when I'm playing games (e.g. Overwatch), the monitor suddenly turns off and the fans start to go really fast, although I can still hear audio. What I've done in this situation is power off the PC, turn it on again and it's back to normal.

It happens very randomly, sometimes I'm playing for over an hour and I don't see any issue, other times after 30-40 min, this error happens.

I've ran FurMark tests for 2 hours straight, and I've had no problems at all, the CPU temperature stays around 55 degrees, the GPU temperature stays around 66 degrees.

Here are some screenshots of what I can see while running FurMark Tests:

I have not overclocked anything, except enabling the X.M.P profile for RAM memory option in the Bios.

Do you have any ideas of what could be the problem or what other tests I can run to pin down the issue?

Thanks for your help


Just in case, these are the components of my PC:

CPU: Intel Core i5-7600K 3.8 GHz QuadCore 6 MB Cache
Video card: ASUS GeForce DUAL-GTX1060--O6G 6 GB
Motherboard: ASUS LGA 1151 PRIME Z270-A
Power Supply: Seasonic S12-II 620W 80+ Bronze Certified
Monitor: ASUS VS248HR
RAM: Corsair Vengeance LPX 8GB (2x4GB) DDR4 3000MHz
SSD: Samsung 850 EVO 250
Hard drive: WD Blue 1TB - 7200 RPM SATA 6 Gb/s 64MB
CPU cooler: DEEPCOOL GAMMAXX 400

Hi, thanks for your suggestions. I have removed the overclocking of the RAM in the bios. The bios is on the latest version 1009.

I did have a look at the event manager, all I can see is that on the time of the crashes, there is a critical event "The system has rebooted without cleanly shutting down first.", which I'm guessing shows up because every time the crash happens I press the power button to turn off the PC.

About the PCI 6-pin connector, I have now connected a different power supply, because I've read in other posts that it might be a power supply issue, even though that power supply I had before is brand new (and so is this one). It seems like both connectors were a little bit loose, there is way to move them side to side, is that normal?

I will give this setup a try and see how it goes, will update soon.

Thanks!

I will bet, that it will be the PSU.

Just had a fully simmilar problem like you, and it fixed it instantly with a new psu.

My own psu had 650W and the new i tried with only had 500W and it still worked better.
reason might be that, some psu's loose a huge amount of wattage in the years going past.

Hi guys, thank you so much for your suggestions, and apologies for taking so long to respond. I was making sure that the problem was truly fixed before replying.

[strike]Since I changed the PSU I've had no problems at all :), I've been able to play for hours without any kind of crash. The PSU I installed has about the same KWs as the previous one.[/strike]

[strike]As a side note for future reference, the PSU I was using when I had the crashes was brand new, so it can happen with new PSU as well.
[/strike]

[UPDATE] Read bellow

Thanks!

I'm adding this for information purposes for whoever ends up reading this post. Two days after writing the previous post saying that changing the power supply fixed everything, the computer shut down again.

I sent back the video card, got a replacement one, and it's been 1 month since I installed and I've had not a single problem with the new one, so I guess the problem was the video card.
