hi, i m having a problem with my graphics card. its an AGP card of 128mb and 5200fx. Its of Geforce(nVidia). From last few days my monitor turns-off and when i move the mouse cursor monitor turns on for a second and turn off again. I have checked there is no problm with the softwares section (like power managment etc.).And even if i restart the system it doesnot turns on but case LEDs are glowing and CD leds are blinking for long. No beeps. Day before yesterday when this happened i turned off the system and back on after 2-3hrs and it was ok. But yesterday it didnt turned oneven after 4-5 hrs. then i thought that agp might hv overheated so i switched on the AC for 2 hrs and got temp down to aroung 24 C but even then it didnt started. then i removed the agp card and ran my system on integrated VGA and it worked fine. and today right now i just put the agp card back and its working again. i m writing this thread on agp running. Whats the problem?? Please help. thanks in advance.
