I'm having a problem similar to this guy. evga.com/forums/tm.aspx?high=&m=667379&mpage=1#669179 Yellow/blue horizontal lines down the monitor. Bios is pretty much unreadable since there numbers and letters everywhere (only in bios/post). When the computer just freezes I can move the mouse and sound plays fine, but after a few minutes it just goes to bsod. As long as the video card is disabled I seem to have no problems, except for one stick of ram, which will only work on the furthest dimm slot. If its moved from there I get 1d and c1 errors. As long as the video card stays disabled, the system seems to be stable. I have ran memtest with no errors also. All parts are running at stock speeds, no OC. I've done just about everything I can think of - reinstalled video drivers, flashed bios, checked temps. Everything looks good. Only thing I couldn't test was the psu (no multimeter). I suppose I could test it with everest? Volts look fine from bios though (what I can read of it anyway) I'll attach a few minidumps (8) from the past few days. specs: evga 680i sli 8800 gtx corsair xms2 D. 2gb intel core 2 E6600 Any help is appreciated.
