Is your machine making any weird beeps on startup?
It could be overheating which is causing it to lock up because normally your OS wouldn't cause your bios to lock up.
Check that your fan over your cpu is connected correctly and is venting correctly. Also make sure your PSU is venting correctly (dont have it too close to any walls, curtains etc)
Finally it could be the wall socket your using, sometimes a weird ground loop in your electrical outlet can cause electrical items to go a little weird or it could be some voltage problems. I suggest you take it to another room (well away from your room) and test it on another wall socket
