Some days back my PC hangs while checking RAM (power on self Test), I have tried restarting PC but dosent work. I have also noticed that my PC hangs at different points while power on self test (it dosent stuck at same location). I have tried changing banks of RAM, Pressed (to check for any loose contact).. After that there was No display !! I pressed AGP card..now there was a display but PC is not able to do complete Power on Self Test. Does Beep(followed by some delay).........BeepBeepBeep(no delay) mean there is no/loose diaplay/AGP card. ?? I have tried almost one day!! working on my PC... I was not able to find any solution to above problem.. Pls help me to boot my PC... Thanks for any replies in advance Shailendra.
