So my old graphic card died, (sapphire hd4870). And i bought a 2nd hand msi hd7970 3gb's. Then when i was playing CS:GO on some situations with more fps the screen goes black. I had OC on the cpu, now its stock. I have already installed windows aand drivers from 0 and format my pc.
On Furmark the computer just restarts like at 5\10seconds.
What do you think? Faulty Graphics card or Faulty PSU??
my system is:
ocz platinium 1600mhz
coolermaster cm690 with 5 vents.
Also good temperatures in every componente.
i'm a litle bit desperated
