Question GTX 980 ti Problem

[ghintipas]

I have a gtx 980ti g1 and when I try to play games after half an hour my games crash and close. My specs are i7 5820k , 32gb ram and 850w gold psu. My gpu is not overcloacked and i don t have thermal problems my cpu is watercooled . I though my gpu was thermal throttling so i tried running 100% gpu fans. And it didn't work my gpu keep crashing usually around 53-55c.I also tried re-install my drivers it didn't work either . I have windows 10 the latest upgrade. Any suggestions?

I'd be looking at the power supply and I'd be monitoring the voltages and make sure they don't go out of spec.
The spec generally is +/-5% from the nominal voltages which are +12, +5 and + 3.3.
You can use HWInfo to do this.....and you can also set it up to log to file so you can see the voltages right up to the crash.

Either I would do this^^^^

OR

Swap in a known good power supply.

I don't have an other PSU so i tried to monitor my voltage ( my PSU is EVGA SuperNOVA 850 G2 )

GPU [#0]: NVIDIA GeForce GTX 980 Ti:

I also saw that the crash happended when gpu hit 100%

Failure after a time smacks to me of a thermal issue.

It could be the cpu because of a blockage or something in the liquid cooler.

Or, it could be the graphics card which is getting a bit long in the tooth.
55c. seems a bit low for a graphics card running full out. I might expect 80c.
Are the gpu airways clear?

My CPU at full load it is like 55-60c . My gpu can't reach 80c beacuse when it reaches 55c it crashes . My gpu airway are clean. My gpu has this temps bacause i set my gpu fans at 100% speed.
