Hey all, recently i swopped my xfx 7600GT card for a Asus 7900GTX. I know who'd be so stupid as to swop a 7600gt for a 7900gtx. Anyway there is a reason for it but thats not what is bugging me here. The 7900gtx is giving me a problem, but did not do so in my friends pc before we swopped. It is creating these small dead pixel like dots on my CRT monitor. Also tried to run 3dmark05 to test the card and it crashed. Last night i started it up again and installed RivaTuner and upped the fan speed of the card to 60%. This seems to have helped seeing as i could run 3dmark05 and dont really see any small dots on the monitor now. My first reaction was overheating and also power supply. PSU being a no name brand 500w, and i dont really like no name brand stuff. Its my wife's pc so i did not care for a name brand when i bought it. My question is this, it seems to be fine now, but seeing as the card is still under warranty should i send it to Asus and see what they say. Maybe teh memory modules or something else is faulty, or maybe they pick something else up. Or should i just put more fans in my pc case and get a better psu?
