My Toshiba Satellite laptop has started to shut down suddenly. Before shutting down it isn't displaying any warnings, error messages, nothing - just suddenly blacks out. Shutdown occurs after about 2 hrs of running. I have also turned off the "automatic restart" option on system errors. Anyone know what's going on here?? Could it be a hardware problem? This is a fairly new laptop of about 1 1/2 years of working. OS- Windows 7.
Thanx for any input.
