Eh... well i first had this restart problem yesterday night when i switched my computer off it just restarted instead but since then it has developed.

I came home from Uni earlier and my computer once switched on will only stay on for a max of 3 minutes before restarting. Peacefully too, no errors, blue screens, weird beeps, noises.... nothing just restarts.

I have no idea why.

Any information of guesses are welcome.
