Hey

Every time I try to play skyrim or any "powerfull game" my pc reboots right after loading scream. Made some tests, memorys n my i7 are fine. I think the problem might be mt gtx 970 or my cooler Master g550m bronze 80 plus.
Ive tried some benchmark like 3dmark or furmark and as soon as the test starts, the pc reboots.
Anyone can help? Please
I run with:
I7 4790k
Mother board b85m gigabyte
Gtx 970 Asus strix
2x 4gb hyper x ddr3
1hd 1t
1 water cooler
Cooler Master g550m bronze
Windows 8 (it was 19 but i tried to reinstall the system)
There is no problem with overheating and o also tried older drivers

Thanks


Sorry for bad english .
 
Solution
If you can, try using the graphics card in another system and see if the problem follows. You are correct, probably the PSU or the graphics card. I would start by replacing the PSU if the card works in another system.

The psu does not have more than 2 years. Is it a bad quality psu? It's cooler Master and has a 80 plus bronze. Maybe i was fooled

Hope its not a graphic card proble, they are very expensive here kkkkkk.

New details, I've tried play skyrim at medium graphics and it worked for like 5 minutes, then the pc rebooted and after the boot, it rebooted again. It really makes me fell like a PSU problem, right?

Yes, i have. And all the tempertures are ok. GPU keeps the 40°C, 45°C. CPU keeps cool too. I used GPU-Z too check some status, and log it from 0,1 in 0,1 Second.
