PC crash's when booting games and stress testing my GPU.

Joshgibbs · Dec 15, 2015

CPU: i5 4690K
Motherboard: MSI Z97 G55 SLI
RAM: 8GB
GPU: Radeon 280x 3GB
PSU: Antec high current gamer 850W HCG
Windows 8.1
Overlocked? Nope
PC is 1 year old.

Whenever I launch games it shuts off instantly and restarts 2 seconds later, usually as soon as I hit the menu. No error message or anything. It also crash's just as I start stress testing with Valley Benchmark. I'm guessing it's either the GPU or PSU but I don't know how to find out which one. Temperatures are not a problem at all, I even cleaned the PC very thoroughly. No success.

I took the graphics card out and could actually play counterstrike on high settings without any crash's, I just used the motherboards graphics. This same situation has happened to me before, but it completely disappeared after 5 days or so but now it has returned. I haven't made any major changes to my PC, software or hardware as of recent, so... Anyone know what piece of hardware is the culprit? Thankyou all for reading.

its either the power supply, the gpu, or the motherboard.

have you tried a different pcie16x slot?

try doing a video driver flush and reinstall to rule out some wonky driver conflicts. though that doesn't sound like a driver issue, its worth a try.

I flushed the video drivers and reinstalled them. No success. I switched the card over to a different PCI slot and actually lasted about 5 minutes in counterstrike. This is unusual but might of been a fluke because I tried it again and it crashed pretty much straight away. When I lasted 5 minutes in counterstrike I noticed my GPU temps were at 63c. This is unusual. I know this is kind of high but is it high enough to warrant a system failure? Pretty stuck at this point. What should I try next?

It's 48c in idle right now.

63c is normal. but it should idle much lower. my gtx780 is idling at 29c, i peak out at around 72c in battlefield though.

on your antec power supply.... it has different 12v ports that your pcie power pins plug into. try moving them around.

that power supply has 2 12v rails, maybe one of them is failing.

try the two on the left, the two on the right.... then try one from the left and one from the right. not really sure which ones are from which rail.

instant full power off seems like a power supply issue. good thing antec has a 5 year warranty.

Ok, I tried every combination with all 4 slots. No success. ;( Thanks for your help so far dude, you got any other idea's?

you could try the cmos reset on your motherboard, but beware your going to lose any overclock settings you have. also after that some bios settings may need to be changed if you are getting an error when trying to boot to windows.

I'll give it a go right now and report back in a few. Thanks.

nikoli707 :

No success dude. I definitely cleared the CMOS but it just didn't help my situation. Should I repost in the power supply section?

nikoli707 · Dec 16, 2015

you can try there and in the motherboard section too. at this point if you can get your hands on a different power supply that would be nice.

Damn. Really don't know anyone who has a spare.
