Recently I've changed my faulty radeon hd4670 for another one. I've also added another hdd. Then lately games like PoP: The Forgotten Sands and Starcraft 2 have started crashing with a grayish/blackish screen with vertical lines and irritating noise. Only the hard reset helps then. I've run some test and concluded that this happens only during prolonged graphically demanding scenes when fps drop below 25fps. If I lower the graphics settings everything runs ok without crashes. I finished PoP with just few crashes somewhere in the middle of the game, while in other parts of it there were none. Same with SC2. Games crash after 2 or 5 or 10 minutes or not at all depending on the above.
I could easily sacrifice visuals for the safety, but still I'd like to know if it's the PSU or the GPU causing the crashes. Any ideas?
AMD Phenom X4 9550 2.21 Ghz
Asus M2N68 Plus
Kingston 3GB (2+1) DDR2 RAM @800Mhz
Radeon 4670 128-bit 512MB GDDR3
2 HDDs
PSU 450w
Win7 Ultimate 32-bit
Yeah, drivers, directx etc are up to date.
