my pc's original problem was that it won't start windows xp (nothing on monitor) with an accompanying beeps (DAAAAAAAT-DIT-DIT-DIT); sometimes it shows a vertical green bar occupying the right half of the screen. used to be an intermittent problem. but yesterday i wasn't able to use my pc totally, no restarting helped. after taking off and putting cards back on the motherboard (the latest being the internal modem), the thing worked (which is why i am able to type this message). but my pc still hangs... AND RECOVERS*, with WinXP telling me that NVIDIA GeForce2 MX/MX 400 is causing the instability. my video card is barely 4 months old and has no problems physically, what could be wrong? i also see the following message in my Events Viewer under Control Panel's Administrative Tools:
"The driver nv4 for the display device \Device\Video0 got stuck in an infinite loop. This usually indicates a problem with the device itself or with the device driver programming the hardware incorrectly. Please check with your hardware device vendor for any driver updates."
please help. i'm not even sure if i narrowed down the problem to my video card correctly. my motherboard's Asus P4S533-X, in case you need the info regarding the "beep" codes. thanks much in advance!
(*WinXP recovers after freezing for a minute, but the monitor's resolution shifts to the lowest and least color quality, like in a safe mode.)
