Have you installed any new programs or hardware recently? Have you trying doing a system restore to a date before the restarts started happening? What you need to do is stop your system from automatically restarting so you can actually get a blue screen that might actually show you some information.Right click 'my computer'--properties--advanced tab--click 'settings' under startup and recovery--uncheck 'automatically restart' under system failure. Also, check your system event viewer (under admin tools in control panel) for error messages during the times that your system was rebooting or during the times you get the error message if you disable the automatic restart.Power supplies can cause random restarts, but I don't like to suggest putting $$ into replacing parts unless I know for sure that they're bad.
