does windows 7 shut off your computer like vista ( like i will be on vista facebooking or something and it shuts off) :@ it cant be over heating cuz i got a cooling pad with a fan so please help with this problem thanx
There are millions of reason why would that happen.
For example, if you are on laptop, then your battery might be too low so Windows is shutting down automatically.
Some viruses could cause shutdowns as well.
Overheating is highly possible (for example, the CPU fan inside does not work or your ventilation's holes are all stuck with too much dust so your cooling pad won't help much).
