    Problem building a new computer... can you help diagnose?

    I'm trying to put together a computer (it's not for my car, that PC is already running great ).

    I build it, plug it in, motherboard LED turns on, I hit power, and everything turns on, but I get no video. No beeps either.

    I take everything out except for the CPU and heatsink/fan, and hit the power button.

    Yes... 1 long, 2 short beeps! I think that means that the CPU isn't dead And I believe that that code indicates a video problem.

    I tried the following combinations: RAM in/video card out, RAM in/video card in, and RAM out/video card in.


    RAM out, video card out: As stated above, 1 long, 2 short beeps.

    RAM out, video card in: 1 long, 2 short beeps

    RAM in, video card out: Nothing. No beeps.

    RAM in, video card in: Nothing. No beeps.

    This seems like bad RAM, but can it possibly be anything else? Why am I getting a video error?

    This is all new hardware, so I don't have parts laying around that I can swap in and out to test.

    Computer specs:

    Intel Pentium 4 630 (3.0 GHz, 2 MB L2, 800 MHz FSB, LGA775, H/T)
    Asus P5GD2-X Socket 775, Intel 915P
    KingMax 1 GB PC4300 DDR2 533MHz 240 Pin Unbuffered
    Asus Extreme AX300SE-X/TD ATI Radeon X300 SE
    Antec Lifestyle Overture II Case with 450W PSU

    TIA for any input!
    '03 Intensa Blue Pearl Lexus IS300

    Specs: Xenarc 700TS, Opus 150W PSU, CarCPU Case, 2.0 GHz Celeron D, DFI PS-35-BL, SB Audigy2 NX, Centrafuse 1.4

    Progress: Car PC up and running!
    To Do: Navigation, WiFi, AM/FM Radio, DVD

    You need to find what that beep code means. Your diagnosis of bad RAM is certainly a possibility, but that beep code is going to give you the definitive answer.

    Check this link, which makes a good starting point:

    According to that, it's a video card problem. That resource isn't the end-all/be-all, mind you.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Under normal circumstances, a signature would go here.
