laptop shutting off without warning

for some reason or another my laptop acts like it crashed and the power stays on and then I have to force the power to go off and when I turn it back on it comes back on and then it says that I got the blue screen on the error and when I try to check for a solution it doesn't show me any solution whatsoever, this has happened to me 3 times since Saturday, any solution that I can use to stop this from happening because my computer is no longer under warranty and I can't afford to replace the hard drive and I just had the hard drive replaced back in April because it crashed and I most certainly can't afford a new computer

how do I upload the logs, could you help m out with doing that

You will want to post your problem in the BSOD Help & Support Forum here:
BSOD Help and Support - Windows 7 Help Forums

The instructions for posting logs and other helpful information are at the head of that forum.
Blue Screen of Death (BSOD) Posting Instructions

If you go to Start > Computer > System Properties > Advanced System Settings > Advanced Tab > Startup & Recovery : Settings Button > Under "System Failure" - is the "Automatically Restart" box checked?

It may be getting to warm causing the shut down. Do you monitor temps at all? Lap tops are known to get dust buildup on the fan and causing a overheat shutdown problem.

I started a new thread in the BSOD and did all the instructions and no I do not monitor the temp of my laptop, is there a certain program that I can use to do this
