    hope someone can help me. I have LGA775 cpu. everything works until i decide to change to a quiet cpu fan. install a new cpu fan and drop a tiny thermal on cpu. everything done. power up computer and no boot, no nothing. only black screen. then a few second later computer turn off itself and then back on. this time it stay on but still black screen, no startup boot or anything. completely black screen.

    cpu fan are spinning and everything seem to function correctly. no beep sound.

    Its possible tht when you were changing over the cpu fan, you may have moved/touched the memory or graphiocs card, so just check that all is ok.

    the only thing i did not check was the memory. graphic card is in and lock. onboard graphic card fan is spinning.
