    DFI Motherboard C1 Error ?

    On my gaming computer I went to boot it up and the screen was locked so I rebooted it and now all I have is a C1 error and no video.

    Its a DFI X48-t2rs motherboard.

    Any idea what the C1 code stands for and what I should do next ?

    Thanks for any help you can give me !

    Is it a C1 error in the bios or when you're booting Windows?

    The C1 error is ram related. Try the following:

    1. Reset CMOS, load Bios Defaults. Test if it will POST .
    2. Try one ram stick at a time in each slot to see if you have a bad stick.
    3. Test with known good ram.
    4. A bad PSU maybe the issue.

    Check your mobo, psu and vid card for any bad caps, http://www.badcaps.net/ident/

    If they look good, then follow the tips in the order I listed.

    Note: follow your DFI manual for clearing cmos.

    I removed the ram chips and moved them to the spare memory slots and the computer booted fine.

    Humm....?

    You need to open up just a little bit more...

    Did you inspect the ram sticks and slots for any damage? Did you try reseating the ram back in the same slots to see if they were just loose?

    ***If there are any signs of burned or bent pins on the ram or slots , do not force the issue. A short across the wrong pins will further damage the components, ex. slot, ram or entire mainboard.

    You can test the ram with Memtest86+, http://www.memtest.org/

    One pass is fine for testing, no errors are allowed. Test with the working slots first. Then try the other slots . Its better to test one stick of ram at a time per slot to see which sticks or slots are bad.

    You should also check your Power Supply voltage rails , the Bios voltage settings and Bios Hardware Monitor are correct. How to
