    start off with some specs... ::
    Motherboard: Asus P4P800-VM
    Power Supply: Antec 500W ATX12V V2.0 DUAL-FANLESS UL FC ANTEC
    Processor: Intel Pentium 4 w/ HT tech; 3.4ghz; 1mb cache
    Memory x2: Corsair 1GB PC3200 DDR DIMM Memory
    Video1: eVGA GeForce 6800 GT / 256MB DDR3 / AGP 8X / VGA / DVI / TV Out
    Video2/3: ((not installed)) eVGA GeForce4 MX 4000 128mb
    Sound: M-Audio REVOLUTION 5.1 SOUND CARD
    HD: WD Caviar Special Ed. 200GB Ultra ATA/100 7200RPM w/8MB Buffer
    CDRW: Liteon SOHC-5235K DVD 16x + CD-RW 52x32x52 Combo Drive (Black)
    DVDRW: Asus DRW-1608PB 16X DVD±RW Dual Layer Drive (Black)
    Fan Controller: Enermax UC-A8FATR4 Aluminum Fan Control
    Fans: 7 case fans + 1 cpu fan

    ok, right now all i have on the board is the cpu, and 1 mem stick.

    basically what happened, i had to get a different motherboard for my p4 processor (old mobo was 1 revision shy of support)... so at this local shop, the guy took my processor off the old board and put it on this new p4p800vm, and the thing booted right up.

    i brought the board home, still with the processor installed.... threw it in the case, plugged everything in and got nothing. so i disconnected everything, pulled the mobo out of the case and its on a school textbook right now... cpu and mem only installed.... plug in power, go to boot, and get a short (.5 second) sound like the p/s is starting up, then get nothing.

    i plugged the power supply into an older system to see if it was that, and the old system booted up fine. even the fans in my new system's case turned on (i overlooked unplugging them). when the p/s is plugged into the new board, the fans DONT turn on.

    so the conclusion i come to is that something in the asus motherboard is not allowing the power supply to fully turn on.

    /pulls hair out

    any ideas? suggestions? ANYTHING!!! SOMETHING!!!!!!

    Short the on/off pins on the mobo with a screw driver. :eek3:

    Don't touch anything else though. :o
