    Seems that something got fried inside your computer (Power supply, Motherboard, etc).

    Well something shorted/fried and the only way you are going to find out is to test each part in a bench or test system. I would start with the pw supply. Dells come with a decent pw supply; not top of the line however not junk either. You can swap in a pw supply for testing. Note you do not need to fully install the test unit. Simply connect atx, aux, and video pw [if used] and hit the ON button. If the motherboard completes POST, then you know the pw supply was the problem. If the system does the same thing as before, then most likely a motherboard failure.

    Note old dells have proprietary pw supplies. The newer models have standard atx type pw supplies. We have no idea what you have since you have not posted specs. It would help if you posted the exact brand, model# and service tag#

    Best Buy/geeksquad is about the LAST place to take anything. If you do not want to do the troubleshooting yourself, take the system to a real shop. By shop, I mean just that a real shop that does builds, installs networks, etc.

    No. Check with friends for a reference.
    Swap in a test pw supply
    Test your motherboard in a test or bench system

    OK, I have already explained it twice; you need to test your board in a bench or test system ie you install your motherboard in a known working system OR do an out of case build with your board and known working parts ie cpu, ram, pw supply, video.
    Short of sending the board to an electronics lab/shop for a VERY expensive diagnostic, that is the only way.

    i would purchase a new power supply from your local bestbuy (you can always return it after the test)
    then watch the above video from 26:42........... (atleast u can rule out a blown power supply if same results)

    Make sure you find out if you have a proprietary pw supply. As I said before old dells do not use a standard pw supply. Newer ones do.
