Hello everyone, I have tried everything but I can't solve this problem alone...

Mostly when playing games but sometimes when using 3DS max my screen just freezes and then I'm forced to reboot. It started happening a few weeks ago.

I checked the event log, nothing there.
Ran all possible benchmarks( OCCT, prime, Uni, Furmark, memtest) they all run fine, temperature also not an issue.

Reinstalled drivers, formatted pc, upgraded to Windows 8.1, checked voltages in bios all good.

Specs:

MSI Z97 gaming 5 motherboard

Intel Core i5 4690

8GB DDR3 Kingston 1333 mhz memory

2x kingston V300 SSD(the old ones)

AMD Radeon HD7870 XT.(Club3D)

PSU Cooler master G550M

This seems like a hardware issue. My first guess is that your GPU isn't getting enough voltage, whether the voltage setting is too low (because of degradation) or the PSU isn't supplying power correctly.

Maybe try setting your graphics card's memory and core clocks back by 100 MHz in a GPU OC utility and see if that changes anything.

Thanks for you suggestion. I've run some more tests, and now OCCT crashes the system after around 45 mins. So i'm happy with this now I can pinpoint the cause. I will stresstest using Furmark, memtest and prime to make sure that it isn't one of the components.

I measured the voltage with a multimeter when idle and under load, the GPU got between 11.96 and 12.05 so that should be fine, also measured the +12v rail when the system was under load it doesn't get below 11.94v.
Also the system run fine during a 1hour benchmark, real strange.

I must say that the measuring and benchmarking where done in a much cooler place then the computer is normally running. But this could be the problem because the temps never go above 65 celcius

I'm hopeless now hehe......
