    What processor are you using? Are you using the standard Intel cooler?

    best thing to do is to go through the trouble shooting steps listing at the beginning of the HW forum. This would involve building the major components out of the case, if your psu wont even turn I would look into that first, ie trying another known working one

    If the processor fans turns 1/4 turn and stops the power supply is working.

    Try this:

    Disconnect the machine from the power source, and press the Power On button for about 10 seconds to drain any residual charge from the capacitors.

    Without removing the cooler take a flat blade screwdriver and turn the locking pins counterclockwise to the unlock position. With all the locking pins loose, without lifting up on the cooler assembly "gently" turn the cooler assembly left and right a couple of times (Just a couple of degrees each way). Turn the locking pin assemblies until the notch on the locking pins are perpendicular to the heatsink. Re-align the locking pins with the holes in the motherboard. Push down HARD on 2 pins at a time diagonal from each other, until all 4 pins are fully down and locked. Instead of pushing 2 pins at a time, you can also push down on the cooler and, push down HARD on each pin individually. Either method works equally well, however many people find that pushing downward on the cooler with one hand, and pushing each pin individually with the other hand is easier. After all 4 pins are down and locked push down HARD on each pin individually again. It is very important that the notches on the locking pins are perpendicular to the heatsink or the heatsink will not lock down.

    After the processor cooler is fully down and locked, re-connect the power source, power on the machine and see if it will POST.

    Try that first. The heatsink has to be in contact with the processor heatspreader with at least 17 (f/lb) of pressure or the machine will not POST or boot.

    Win2Kpro - is this an issue with Intel Coolers or with this socket designed period? My aftermarket coolers seem to CLICK in without a problem, I never tried with the standard Intel cooler.

    I believe if you will try it with an Intel cooler you will find that it will work the same as a 3rd party cooler with the push pins. The big problem is people are use to ZIF sockets and just don't put enough pressure on the pins to get them to lock down fully.

    The reason you see this more with Intel coolers is the fact that the boxed processor comes with that cooler so more people initially use it. I've built a lot of socket 775 machines, and after the first time, I've had absolutely no problem with getting the cooler to lock down.

    I like the design. I've only had to do two in field replacements and I can do a complete replacement including cleaning the processor heatspreader and installing a new cooler in about 20 minutes.

    In my opinion, at this point I would see no reason to suspect the board is defective. The symptoms you describe generally indicate that the cooler is not fastened down properly.

    If you followed my instructions you would not need to buy any compound, since I tell you NOT TO LIFT UP ON THE COOLER.

    NO, you cannot use toothpaste as thermal compound.
