HELP! Online diagnostics

[Guest]

My laptop is experiencing some hardware problem. It keeps suddenly turning
off quite often and usually I have to wait at least 1 hour to start it to
work again. Is there any online diagnostics program that can scan my PC to
find out the exact hardware problem it has? Somebody please?!
