PC getting restarted

Hi All,

My comp is getting restarted again n again. Can anyone help urgently?
Thanks in Advance.

Right click My Computer,
Properties,
Advanced tab,
Settings button (Startup and Recovery),
uncheck Automatically Restart.

I believe the hard drive has failed/crashed. Install a new one and reinstall the operating system/Windows XP. Have had this happen to me and it was the hard drive gone bad.

Same thing happened with me. That was power supply problem, my electricity meter box had some sparks or short n fluctuating power supply. Ask any electrician to fix it. Hope it will help.

It sounds to me like you're having virus/malware problems. Try cleaning it all up.
Check for latest antivirus with new updates.
