My first suggestion: open up your pc and clean off all the dust, especially around the fan area. Second: if that does not work, completely wipe your pc and reload windows 7. A virus may have gotten into your pc, and that is the only way to get rid of it.

I was having similiar problems with mine and it turned out to be the fan that need cleaning, it's fine now. Don't know if that could be the problem or not but you never know!

It could be there is a problem with the memory.Or a recently made hardware/software change could causing this.There is too much dust in the RAM or it is loose.A virus has got into your computer and causing it to shut down.There are umpteen reasons why this could happen.You need to exhast them one by one.First check the hardware.If it is all fine then the best thing is to format the computer after taking a backup.
