    I am working on a Dell Optiplex 620 that won't boot. I am getting beep codes, but don't know what mb bios I have. The mb is just marked Dell and I have the s/tag. How can I find out? Thanks

    In short you cannot. No one knows if the bios was updated at some point. If you just mean what type ie ami, award, etc, then dell uses a phoenix/award type bios.

    Stock BIOS listed as A11. Just curious why do you want to know what BIOS you have?

    If this is a Dell Optiplex GX620 the beep codes for all 4 models of the machine are available on the Dell site.

    Sorry that was a stupid question.But wouldn't expect beep codes to change even with an updated BIOS.

    I just wanted to know if I needed to flash the bios. I am getting 4 long beeps and then 2 short ones. I am guessing it means keyboard error...but...how do I fix that when it won't boot???

    I can guarantee you that flashing the bios is NOT going to fix your problem.

    Start with some basic troubleshooting. Open the case and reseat the video card and ram. Make sure the slots are clean; use a can of air to blow them out. Reseat the atx power connector [4pin if used also] Pull the pw connectors from ALL of your drives both hd and optical. Now see if it will pw ON and complete post. If it does great; shutdown and connect devices one at a time until you find the failed part. If it does not post, then swap in a known good pw supply for testing. Still no post and I would think your board has failed.

    Thanks for your help. I kept fooling with it and it finally booted. I got an error message that the system battery was low and the time was incorrect. I went into setup and changed the time and shut down the system. I then reseated both memory boards and unhooked the sata power connectors on all the drives. It has pci connections, so I don't know what to do about the video reseat...I then tried to boot again and kept on getting the beeps again..after leaving it off for 15 minutes, it finally booted. I checked the ps and got 4.9 v and 11.8v which, I think are within limits...right? I am now running a Hirens and doing a mem check while it is running...any suggestions now while it is on?

    Yes, first of all hirens boot cd is illegal and any reference to illegal downloads will result in your thread being closed.

    Next 11.8V under a no load condition is pretty low. The 12V will drop even lower when stressed.

    do the beep codes for the Award bios tell you anything? I think it is 4 long and then 2 shorter (not quick short ones)

    Fit a new CMOS battery, usually they are type CR2032 (silver coin shaped about 1 inch diameter).

    If after fitting you get an onscreen message that the Bios needs setting up that's normal, set it to defaults and set the correct time. It should remember the time now.
