What to do if a computer does not turn on

Steps to take when a computer does not turn one:

  1. Check the power cable at both ends and test the power outlet. 
  2. Review these procedures Diagnostics and Dell_Computer_Diagnostic_Codes
  3. If the computer crashes with a blue screen of death (BSOD), record the BSOD message. If the BSOD screen flashes too quickly, keep tapping F8 during BIOS load until you get an option to "Disable Automatic Restart on System Failure". 
  4. Reseat RAM, CPU, hard drive, power cords inside computer.

CMOS - System Battery is Low

If you get a message that the CMOS battery is low, you can continue booting by pressing one of the function keys (F2 usually), but you need to change the CMOS battery soon.

Floppy Diskette Seek Failure

If you get a "floppy seek error" message you should try disabling the floppy diskette drive in the BIOS (even if there's not physical floppy diskette drive in the computer, someone may have mis-configured the BIOS to think there is one). Usually the option to disable the floppy is available under the Drives section in the BIOS.
