I bought a new rig in December 2013 for playing games and noticed that every game i play crashes to desktop withing 20-40 minutes of playing. But in that time I can play games without any problems with decent fps. Apart from games my PC runs absolutely fine. I tried updating GPU drivers, .net framework, etc, removing and installing all parts and also resinstalled windows but it did not help. So thinking that my GPU would be defective I RMAed it and got a new GPU and also new PSU. After installing them the crashing seemed to stop for about a month and started happening again. I monitored temps while gaming and they were all fine (60-70 degrees).
Specs:
CPU - i5 4670k (not overclocked)
Mobo - Asus Maximus VI Gene
GPU - MSI GTX 760 TF OC
RAM - Kingston valueram 2x4GB
PSU - Corsair TX 650 V2
OS - Windows 8.1 pro x64

things i tried:
memtest86 for 6 hours with no error
msi kombustor for 1 hour with no error
updating drivers
updating all softwares
reinstalling drivers and softwares
clean boot
reinstalling windows
updating bios, clearing cmos
reseating gpu and ram

things yet to try:
reseating cpu
prime95
any voltage changes
leave gaming :( (if everything fails)

seriously? the card can fail in a month the same way? I mean the crashes happen the same way as before.

yes exactly same thing. though i remember that crashes on second card started happening after i installed ghost recon phantoms and there was power cut right after turning on my pc (just before the bios screen).
 


The power cut may have affected the card or any other component, since you ran memtest then ram is not the issue and the card is most likely followed by motherboard. Any chance you can try the card in a friends computer to see if it takes the symptoms with it.

I will try that but I am still not getting that even if the card is damaged how can it be the same way as previous card? Can cpu reseating help because i reseated cpu before installing new card.

gpu is factory overclocked but the ram is not overclocked

 


It is hardware, it sometimes just fails. Different things can be wrong with it even though the symptoms are the same that is crashing. If it fails in two systems we will know for sure.

hmmm seeing as you RMAd the card, then even though it's unlikely the replacement card has a similar issue

or, which is possibly more likely, the problem lies with another piece of hardware in your system, eg the mobo

Does you have another computer, or a friends PC that you test your GPU in?

Actually before I had Asus GTX 770 DC2OC which i RMAd but i got its refund and bought a MSI 760 and corsair PSU. Even i think that its not GPU but a different component but i cant seem to figure it out.

If the board broke now then previous card should have run fine. Can processor be defective because as i said i reseated cpu before installing new card.

have you checked your windows event log to see if there are any reported errors around the times the games are crashing?

also, might be a bit of a long shot... but have you tried with your AV turned off?

Only ask as I had a problem with games freezing on me in the past and it turned out I had to re-install my AV to fix it.

yes i checked event logs and every game crashed with 0xc0000005 error with faulting module either that game's exe file or nvwgf2umx.dll. I will try running games by disabling av.

ok so the problem seems to be fixed as of now. Here is what i did, removed my 760 and switched to iGPU, then reseated processor and reinstalled 760. This rules out that my graphics card, psu and ram are faulty so either motherboard or processor must be the problem. anyway to check these two for fault?

It is fixed now but dont know for how long. iGPU had the same crashing problem but after some more time (50-60 mins). Maybe reseating cpu has helped but i fear it should not happen again.

It happened when i forgot to turn off the switch after power cut so maybe surge or spike may have affected it. but then again i have connected my pc to surge protector. Anyways if it happens again i will RMA my motherboard. How likely the processor could be defective?
