Strange crashes while gaming

[Muddy Muxx]

Hello to you all.

So i've just finished my first liquid cooling build ever and it all looks great, and temps have become much better as expected. However, iam now starting to experience strange crashes while gaming, after some time, my pc will lock up completly and show a solid random color on my screen, after reading around people say it can be anything from vram, GPU, CPU, ram getting to hot, a failure in vram, GPU, mobo or PSU, more on this later, or driver/bios/directx 11 problems.

So after reading around i tested out with Furmark, AIDA and Memtest to see if i could replicate the error, and after running hours of all test nothing, also flashed BIOS back to default setting to see if it was my oc on my CPU that caused the problem, also dial my GPU down to stock speeds, still get the crash. Altho after a second test of stressing the CPU my system shorted out. And panic began, i found out my PSU had decided to die on me, so running on a different i have laying around no problems booting, and the problem seemed to stop, i also noticed after changing to the other PSU, better say its a Corsair HX650, the one that died on me was a HX750, my volts are way different, CPU volts went from 1.220 to 1.160 and GPU went from 105% power to around 95 while gaming, so seems to me it was delivering more than it should so a good indicator that it was going basicly. But i have still experienced a crash like mentioned, i have tried rolling drivers back and forth and yeah basicly done everything except trying different mobo and GPU, since i don't have that laying around to test, so in that case i will have to buy all new, so would like to see if that is really necessary. Have a fear it will be a reality, since i guess there could be a chance that the faulty PSU has taken something with it.

So my system:

Asus P8Z77-v Deluxe

Intel i5-3550K

Corsair Dominator Platinum 2x4gb

EVGA GTX670

OCZ Vertex 4

Corsair HX650 now, before was HX750

 

Temps on GPU is around 45 full load and CPU 55 full load.

 

I hope someone here have and idea to what could cause this crash, since it getting pretty annoying, when running dungeons in Guild Wars 2, and have to hard reset the system while being needed.

And i can't for the life of God not figure out what the problem could be anymore.

 

Muddy out.

what kind of block do you have on your gpu ? and just take the time to redo your overclock

What Nvidia driver are you using for your 670? 320.18 is known to cause problems. This seems like a driver issue to me try driver 314.XX and report back.

I have XSPC Razor block on my graphics and have also tried draining the loop and refitting it to see if it was a problem with contact on the memory or anything.

I ran 320.18 before have tried updating to the beta driver 320.49 will see if i can recreate the problem with the 314. and see if that would be the problem.

Do you think that there could have been created problems from the dying PSU? If it's possible that it could have damage power phases or something like that in the failure? Taking this from that with the old PSU i got the crashes way more frequently than i do now after i switched.

From your fist post it seems like your only locking up in games which leaves me be believe that it's a driver issue . If you want stress out the computer I would grab a copy of prime 95 and run that see if your system is stable don't worry it's a free program and it will let you know by freezing or BSODing that your computer is unstable.

See your logic, prime95 have also been used to test and no problems, so seems about right with it being a driver issue, just feels strange that it only occurred after i put in my liquid cooling have had the system for almost a year before that and never had a bsod or the crashes i experience for the moment, and then i was running oc on both my cpu and gpu.

Have a little new info about my problem, maybe it can help clarify exactly what goes wrong. Just did a little oc on my graphics to see how it would fare since i hadnt had any crashes after i reset everything to stock. So i made it to core: 1241mhz, memory 7ghz with temps on 47. It ran through a heaven bench no problem, just as i started a game it didnt take 2min for it to crash in solid colors, so is that enough to say it's something driver related?
Atm i am trying to see if i can get it to crash again with stock settings, but so far its doing fine. Just wanna figure out if my work bonus should go for a 700 series and maybe a new psu instead of the backup corsair hx650 i run now.
