Hey all, just wondering if anyone could help? Running on an Athlon64 3200+, 512mb 2700 RAM and a Gainward 6800LE. The wierd/annoying problem is when I start gaming I get a blank screen after a few minutes. I've upped the PSU to 400watt thinking that may be the cause also tried driver versions 61-66.93 even the 71's but with no luck. Have run 3dMark and it seems to last without going blank although it has done once, the main problem seems to be in Call Of Duty as this goes blank near instantly. Faulty card? Or am I missing something, temperatures are fine and I've disabled various power saving options in both windows and the bios after reading some threads regarding those possible issues. Any suggestions or help welcome Thanks in advance.
