Are all the power cables plugged in? Which fan is spinning? Does the CPU show in the BIOS?

Also, Welcome to TPU! :)

yes, the power cables are plugged in. My pc doesn.t start. The light is on, cpu and power fan both are spinning, but the monitor is not showing anything. I tried with and without video card still the same thing. If i put a p4 dual core 3ghz is running. Ram is 667 mhz. Could this be the problem? I tested e6550 on another mb and is running. Thanks ! :)

yea you need f6 and it does not officially support them. intel 945 chipsets never had offical 1333fsb support. people like giga and asus et al just added the micro code so they should work.

it will boot at 1066 fsb and you need to oc it to 1333 fsb and drop ram ratio to get it working.
