Dell XPS400 won't boot up after BIOS update

  1. Hello guys, I'm new to this forum. And I hope I find a solution here.

    It all started when I was updating drivers and came across updating the BIOS on my working Dell XPS 400. After Updating it, the BIOS was flashed. Once it rebooted a Post showing came up and at the bottom it said "BIOS updated successfully. AFTER that the computer made a total of 6 long beeeeeeeps with no display, monitor light is orange not green. So I shut down the computer and try to turn it on...it turns on for a half of a second and powers down...after 3 seconds it turns on...however no Display...no light on the keyboard or mouse..I just get those 6 long beeeeeeps one after the other.

    I tried the following:
    -removing battery for 30secs=Did not work
    -removing battery for 30mins=Did not work
    -Clearing the CMOS, moving the jumpers from 1/2 to 2/3=Did not work

    I was read some similar problems and most say the Mobo could be dead. How could a simple BIOS update cause this. There has to be a solution. Anyhow I yet have to try removing the RAM, Vcard, any other attached hardware inside to see what happens. I cannot hit any keys on a keyboard that does not respond aswell..so that holding the insert key=Did not work

    Here are my specs:

    On some motherboards removing the battery, in and of itself is not enough. You need a jumper. List the model number of your motherboard.

    He already used the jumper.

    BIOS updates cause motherboards to become paperweights all the time; it's not a recommended procedure for general purpose PC users. the flashing process may seem simple, but it's very important that you do it carefully. without a stable BIOS, a motherboard is useless. If you've made a backup of the original BIOS, which is highly recommended, flash back and try getting the computer to boot. you may have downloaded and flashed the wrong BIOS file. been there...

    Make a back up of the BIOS? What are the steps in doing that? So in the future I don't even flash a bios and if I do..i'll have it backed up.

    Well yes i put the XPS to rest..looked everywhere for an answer on how to fix it. And I don't plan on buying a BIOS Chip from BIOSMASTER because is not 100% it will work.

    depending on what tool you are using to flash the BIOS, you should be given the option to back up the original programs as a .bin (binary) file. i always recommend that you do this because things fail, and then you may be out of luck. i've bricked one or two motherboards, and it sucks, but you just need to be cautious and do it correctly.

    as far as buying a new BIOS chip, try BIOSMAN.com, i've used them before and they have decent prices.
