My father has a Toshiba Satellite P755-S5215 laptop with Windows 7 and an Intel inside Core i3 processor. It has occasionally had the issue of turning itself off randomly during boot up, upon logging on, or shortly after logging on. However, it has become much more chronic ever since I hooked it up to use the television to use as a monitor. I plugged it in using a 15-pin monitor cable. The computer was off when I plugged it in and when I removed it. I don't know for sure if the two events are related. Could somebody please help me solve this? Thanks.

Have you checked to make sure the fans are running and the vents are clear? Overheating will cause your computer to shutdown trying to cool itself. I'm assuming this is a laptop. You might have to open it up and clean it out with some canned air. I'd look into this before looking for anything else.

Never mind this thread, I'm closing it now. My dad called Toshiba's warranty center and is sending it in. Thank you for the quick response, golddust.
