Thanks for replying Jelly Bean, I did as u said..the computer boots but,when i play any games or high resource consuming app,my ccomp freezes and i have to restart..my GPU temp is around 50C when idle and goes to around 60c when playing a game..

hey, My PC freezes on booting after showing the manufacturer's logo(i can't access bios when this happens)..if i wait for 2-3mins i get a black screen with this message: Intel UNDI,PXe-2.1(build 0.82) ... for realtek RTL8139(X)/8130/810X PCI Fast ethernet controller v2.20 (060711) PXE-E61:Media test failur,check cable PXE-MPF:Exiting PXE ROM DISK BOOT FAILURE,INSERT SYSTEM DISK AND PRESS ENTER I can boot the comp after restart(after seeing the msg.)... Is this a hard disk error..?? plz help..:confused: one more thing: I have a XFX Nvidia 8500GT graphic card..when i play a game(like PES 2010) it runs fine for 5-10 mins..then it freezes and makes a loud noise and i have to reboot..plz help..
