    I have this problem on my desktop computer. the CPU will boot fine and it'll reach the desktop. however, after few minutes of being in the desktop, it'll hangup and suddenly turn off, giving you in the monitor saying "there is no signal". The cpu LED turns off but the power LED is still on. The next time you turn on the pc, it wont boot and the cpu LED wont turn on either. however, if you left it first for about a few hours, it will boot up again until the desktop and a few minutes, will hang up and turn off again. Is there a problem in my CPU or mobo?

    Welcome to the forums chris1017.
    This sounds like a heat problem. Make sure the fan on your cpu is running.
    You can boot into the bios and check the temperatures and voltages.
