Fix windows 7 shut down and restart by itself .....

[traiviet999]

I have old laptop with windows 7 installed. The system shuts down and restarts recently by itself several times before it works. Is there anyway way to fix it?

Thanks

any error message? BSOD?
Right click on My Computer==>Properties==>click Advanced system settings==Advanced tab==>click the THIRD settings==>check off automatically restart
it'll give you the error code if your PC restarts by itself.
