    When I turn the PC on, all the fans run except the one above the heatsink on the mb. and noting shows on the monitor...basically the comp doesnt start. The heatsink is hot, however. what are these the symptoms of? fried mobo?

    Maybe fried video card.

    See if you can hear the hard drive discs spinning.

    well if the vid card were fried, then how would that effect the fan over the heatsink over the processor to be not working?

    It wouldn't. Buy a new CPU fan, they're like $10.

    I would suspect a bad motherboard, or possibly, but less likely, a bad CPU.

    bad? its been running for some time now, if anything, theyd be fried, not defective. the odd thing is, is when u turn the comp on, itll shut itself off after a minute (im suspecting thats due to it overheating, cuz the fan isnt getting power) but the heatsink is real hot. so if the motherboard was fried, then how is the processor still heating up?

    I'd replace the CPU fan first. Some MoBo's won't post by default if they can't detect the RPM for the CPU fan (I found that out the hard way when I switched heatsinks one) or it could be the CPU is heating up too fast with the fan not working and the Mobo has a thermal protection feature. It is a P4 by chance?

    if you are not getting anything on your monitor...check the power supply...i had two cases of this....otherwise its the mobo.

    P4 is intel, and some of them get hot fast once you turn on the PC. If you replace the fan and it still won't boot I would look at the RAM next. If you have two sticks, try taking one out at a time. Also take out all the cards other than the video card. THEN I'd start to consider the MB might be damaged.


    edit: Jeebus christ. I mis-read your post as "no, it's NOT an amd processor". Some of the AMD cores do heat up fast. Anyway, just go with the cheap and easy stuff first.
