Recently i build a new system (8gb ram, i5 3570k, Asrock extreme4-m) with the sapphire HD 7870 Overclock Gigahertz edition. Every now and again (so far every time im gaming) the card crashes with a black screen and a buzzing noise i thought this might be because i overclocked it a bit too much the stock was 1050Mhz i boosted it up to 1200Mhz and i slowly lowered it because of the crashing now im at stock and its crashed so im worried that i got a bad card? is anyone having this issue? Is it a driver problem?
any help would be much appreciated
