Q: I was installing win XP...my computer starts giving beep sounds I tried to replace Hard disk with new one & RAM too but of no use. What problem will be there. the beep sound is long
A: http://www.computerhope.com/beep.htm You will find the beep codes there. I believe that one long beep indicates a video (card) failure. Sometimes removing and reinstalling the card will clear that error. When you don't know an error code don't just shotgun your repair attempts. That's pointless and can lead to more problems.
