    I changed my motherboard from an old one that wasn't detecting hard drives. I power on my system and it starts up (mechanically) but there is no video output on my display. it automatically power off after 2 or 3 seconds. then it retries and same result. then it gives up. I have tried various changes in the hardware config. such as how the power is hooked up to each other. I have a lot of "power sharing" configs; i don't know how else to explain it. lot of hooking.

    what could be the cause of it not starting. It's an Abit IP35-E motherboard. when the power is hooked in there's a bright red light ( i assume thats the display of power going through the motherboard). I'm almost certain my computer is just failing POST.

    Using onboard video or separate card? Does it shut down and fail to post or stay on and fail to post.

    I am using a socket 775 Pentium D 930 3.0 ghz Intel Processor. with its original heatsink.

    I also have an Nvidia Geforce 7900 video card installed. I am not using onboard video I don't think.

    When you pulled the processor and cooler, did you clean the processor heatspreader and the heatsink, and re-apply fresh thermal compound or a new thermal pad?

    There was a power socket (i believe) above the cpu heatsink area where i had connected a power cord. it wasn't a perfect fit it was only four of 8 holes. when I removed that the pc started and continued to run. no beeps were heard. the only problem is the display wasn't functioning . it remained blank and never showed signs of input. I removed and reinserted my video card (which does start up). still no response. the pc runs, no display.

    as for the thermal compound. I had re-applied it, but i decided to completely scrape it off since a little of it got under the cpu. i wiped the cpu off as best i could and there is a little white streak of what glue used to be on it. but it's very minuscule.
