Computer Won't Turn On

Try these steps when your computer powers on, starts to load Windows, but then freezes, stops, or reboots over and over again without generating any kind of error message.

The stopping, freezing, or reboot loop may happen on the Windows splash screen as shown to the left or even on a black screen, with or without a flashing cursor.

Note: If your computer won't start and you see a blue screen flash or remain on the screen, you're experiencing a Blue Screen of Death and should use troubleshooting guide #6 above.

Important: If you suspect that the Power On Self Test is still going on and that Windows has not yet started to boot, a better troubleshooting guide for why your computer won't turn on might be #5 above. It's a fine line and sometimes hard to tell.
