    I just built another system and its just giving me a headache, I have never had such a problem like this. Nothing will come up on my monitor, i replaced my CPU and motherboard and still nothing up. Im not sure if its the videocard, or not enough power supply but here are the specs

    BIOSTAR I915P-A7C Socket T (LGA 775) Intel 915P ATX Intel Motherboard

    Intel Pentium 4 541 Prescott 800MHz FSB 1MB L2 Cache LGA 775 Processor

    160 GB SATA HD

    350 Watt Antec powersupply

    X800XL PCI Express

    I would try the video card first. Do you have a spare that you can try it out with first, maybe try a friend's or something?

    That is not really enough PSU for an X800xl and a P4. It may not be the problem but 350W is pretty sad for that system. P4 and new video card requires a stiff +12V capacity, 17A at least.

    P4 requires a seperate square 4 pin connector on the MB or a 24 Pin main connector to deliver extra 12V to the MB. Some MB need the 24 pin, some you have to split it and use the seperate 4 pin. A budy just had a problem with this.

    PCI-e SLI MB's also have a seperate 4 pin in line connector near the PCI-e slot which may require a power supply connection (but shouldn't uless you are using SLI).

    Connect PSU to the MB with just the CPU and RAM and turn it on, see if it spins up and flashes the keyboard lights (CPU is booting and running bios POST). You should get some beeps for "bad video" with no card installed. If this works then the PSU is probably just too small.
