  1. My PC will work just fine as long as you dont do anything. It will stay on all night but when you try to do anything like install something or go to control panel it turns off. It wont turn right back on you have to wait for a few minutes. Everything been reinstalled and reformatted. My brother had the computer before me and it worked fine for him for 2 or 3 years. Any advice would help. Thanks

    Turn it off.
    Open the case
    Clear out the dust in it with compress air.

    Also check all fans and CPU one too.
    Check all connections inside and out.
    Could be a bad keyboard or mouse

    Just have to track down the problem.
