I keep having the same problem!! My monitor shuts down in some specific games, the sound makes a weird loop(like if i was shoting it does like BANG BANG BANG and then only BA BA BA BA BA and then it simply stops -_-") and the most weird thing, the computer keeps working! i cant see anything in the screen but the light's still on and I still hear every fans working in there... So far the games were this ocurs are: -"Gunz"; -"Fiesta"; -"Unreal tournament 2004"; -"Vampire the Masquerade - bloodlines"; And sometimes CS:S I said it wasnt overheat beacause my temps hardly rise during those games (i checked several times) and if it was overheat the computer would shut down as well(I think) Please Help me fix this, IM GETTING DESPERATE!! Best Regards PS: This already happned when I first bought the computer, but not so frequently. AMD ATHLON X2 5200 2.6ghz; ASUS M2N-E SLI; 2GB DDR800 KINGSTON; ASUS GF8600GTS; Seagate 7200rpm 320GB;

Check the monitor

How do I do that? AMD ATHLON X2 5200 2.6ghz; ASUS M2N-E SLI; 2GB DDR800 KINGSTON; ASUS GF8600GTS; Seagate 7200rpm 320GB;

I don't think it has something to do with the monitor. More like a power supply issue. Is it powerful enough? Not sure but I imagine 8600GTS needs 450W PSU with 18amps on 12V rail. Asus P5K SE E6750@3.3GHz 4096MB A-Data Extreme 800 GF 7900GTX OC'd XP Pro & Vista x64

Its an LC-POWER 550W Dual Rail 24V, is it not good enough? AMD ATHLON X2 5200 2.6ghz; ASUS M2N-E SLI; 2GB DDR800 KINGSTON; ASUS GF8600GTS; Seagate 7200rpm 320GB;
