My computer(my other one, not this one)for some weird reason will keep shutting off on it's own and it usually does it when I click the mouse on something, say like sending a an email or submitting something. And it won't turn on unless I turn off the power from the back and turn it back on. This happened once before too and then I changed the mouse from the regular mouse port to a usb port and it was ok for months and now it's doing it again. I cleaned out the dust in the computer, power supply and it didn't help. So I don't know what the problem could be, I'm guessing it could be the power supply.
