Hi, I recently built my own computer, it worked fine for a while but now is shutting down like it's overheating (which its not) I have to unplug the power supply for a few seconds before it can turn on again. is there any diagnostic programs that check everything from the power supply to the video card?

what are you doing when it shuts down? playing games, browsing, etc. I had issues when I was playing games that used DX11 - my computer would lock up and I had to hard reboot. I turned DX11 off and it worked flawlessly. I also use an ATI Video card (sapphire hd 7970)

It might be the power source or something is causing a short circuit somewhere.

When you can only turn the PC on after power down by unplugging the power cord, it normally means one of the PSU's protection circuits kicked in.

Try a different power socket.
If that does not work, unplug un-critical devices in the PC to track down the culprit.

a different power socket, do you mean the outlet of the literal spot where the power supply connect to the cord?

You could try removing one piece of hardware at a time to see if it continues stuttering. I would start with removing all but one stick of RAM ( don't know how many you have ); then CD burner, and any extra hard drives if installed. If you have onboard graphics, remove the GPU.

Like I said before it has something to do with the PSU. Try/borrow another PSU and see what happens...
