XPS 420 error diagnostic light 1 2 3 no boot cant even open BIOS

This question is not answered

The subject is pretty much self explanatory i guess, the system cant boot, cant even get to BIOS, the diagnostic light 1 2 3 lights up no BEEPS

The other thing is the fan was sounded like its about to start but then it stops...

PLEASE I NEED HELP! ANY THOUGHTS WOULD BE APPRECIATED! I NEED TO GET THIS THING TO WORK....

  • Lights 1,2,3 is the dreaded "Another Failure had Occurred" . Generally this means the motherboard is gone. But to check further, you can try.

    Replacing the CMOS battery. This is the coin cell CR2032 battery on the motherboard. The run around $3-5.

    Normally if it is a power supply issue the power button will light either steady or flashing.

    Another thing you can try is to remove all the ram and plug in cards and disconnect the power on all the internal drives and see if that makes any difference.
