    Just finished putting together my new comp. today but when I power it on, noting shows on the monitor and the Q-code LEDs are giving me "58" (CPU self test failed or possible CPU cache error). I need help figuring out just what exactly is wrong and what I can do to fix this.

    Here re my specs for what it's worth:
    CPU
    Motherboard
    RAM
    Video Card
    Power Supply
    HDD

    [UPDATE]

    Taking out one of that RAM cards has worked and everything is running just fine. Why does my CPU fail when I have both cards in?

    Make sure you're following the instructions on where to seat your ram for your motherboard.

    Genius, maybe he accidentally plugged them into the CPU socket.

    - Try to reset the BIOS
    - Test the RAM modules individually, in all sockets.

    If a memtest gives errors with a certain module or using a certain socket you know that the socket or module is broken.

    I can't reset the bios because it doesn't even show up.
    The memtest doesn't yield anything.

    It seems that the problem lies with the B1 and B2 ram slots. Everything works fine when either ram card is plugged into the A1 and A2 slots but not the B1 and B2. I am running my computer with the cards in the A1 and A2 slots and things seem just fine. still bugs me that the other two wont work.

    If it works with 1, and he's putting the ram in the wrong slot (dual channel) than it could cause the issue.

    Yeah, make sure they're in the same colored slots.

    There is a jumper on the motherboard that allows you to do it. If you cant find it, take out the battery for about 2 minutes.
