My compact presario desktop giving me problem as soon as I change name in an account and surf internet at the same time, after which the screen shows error and can't reboot my PC. Later when I try to on the PC it has got "knocking sound" from the CPU. May I know where can I get it repaired as my warranty is over. According to my friend it could be due to PC card that need to be replaced, is it true?Please help....
