For some unknown reason my computer keeps randomly turning itself off, it tends to happen late at night(after 11) and Ive got no idea why. Anyone?

You don't have some auto shut down thing on your computer do you? Try your antivirus software first.

It could also be CPU overheating and it's turning off as a safety thing. If that's the case, you might wanna think about getting a new heatsink/fan.

Go to Control Panel > Performance and Maintenance > Power Options, see if there's anything unusual...

Would it be the CPU fan or the computer fan? And err, what temperature does the CPU turn off at?

Usually CPU fan, AFAIK. The CPU temp your machine shuts down at will depend.. could be 50 degrees C, or above. There's usually a setting for it in your BIOS (when you boot, there'll be a prompt saying something like "press DEL to enter setup", should be in there somewhere).

There should also be a setting for the temp it turns off at. The critical temp also depens on what CPU you've got.

Surely it wont take 11/12 hours for the temperature reach the shutdown temperature though? And also, once its been off for 10 minutes and cooled down so to speak, it would mean that Id be able to turn it back on without any hitches? Well after the first shutdown it generally just keeps turning off almost as soon as I reach windows - and sometimes doesnt even start at all. I also have to unplug the computer at the mains rather than just turn the power supply off/on. Any other ideas?

Is your fan working properly, or is it covered in dust?

Move into a colder room and try using your computer.
