Troubleshooting: My Computer Won’t Boot

February 19, 2015

If your computer won’t boot, here is a list of things you can try before you call us.

  • I push the power button and nothing happens. No lights. No noise. Nothing.
    • Check both end of the power cord to make sure it’s plugged into both the computer and the power strip or wall.
    • If plugged into a power strip, make sure it’s turned on.
    • Try plugging the computer into a different socket or outlet.
    • Look on the back of the computer near where the power cord plugs in. Some computers have an on/off switch back there. If your computer has one, make sure it’s plugged in.
    • If it’s a laptop, check to make sure the power cord is securely plugged into the transformer (the brick like box that is part of the power cord).
    • If this is a laptop, remove the battery and unplug the power cord. Press and hold down the power button for 30 seconds. Now put the battery back in and plug it in and try again.
    • If none of that works, call us.
  • I push the power button and lights come on but nothing ever displays on the screen or something does display for a second but then the monitor goes blank.
    • Try connecting a different monitor to the computer.
    • If that doesn’t help, call us.
  • I push the power button. Lights come on, but I get a message about a boot device or non-system disk or disk error or NTLDR is missing or anything like that.
    • Unplug any flash drives and external hard drives that are connected to the computer and remove any CD’s or DVD’s that are in the drives and try again.
    • Call us
  • I push the power button and the computer starts to boot, but hangs.
    • Call us.
  • I push the power button and the computer starts to boot but then suddenly goes off.
    • Call us.
  • The computer gets a blue screen with white text that talks about an error.
    This is often referred to as the blue screen of death (BSOD).

    • If you made any hardware changes to your computer, change it back and try again.
    • Call us.
  • Computer goes into startup repair.
    • Let start-up repair run.
    • If start-up repair hangs or runs forever and never finishes, call us
    • If start-up repair finishes but when you reboot, it goes back into start-up repair, call us.
  • I get a menu that lists start-up repair, safe mode, safe mode with networking, etc.
    • First, use the up and down arrow keys to highlight Start Normally and hit enter on the keyboard.
    • If that doesn’t fix it, highlight start-up repair and run that.
    • If that doesn’t fix it, call us.
