HI.. MY COMPUTER PACKED UP A COUPLE OF WEEKS AGO.. JUST WENT DEAD.. I TRYED TO TURN IT BACK ON AND ALL THAT HAPPENS IS THAT THE LIGHT COMES ON, ON THE MOTHERBOARD, THE FAN GOES ON, BUT I CNT HEAR NO BEEPS SOUNDS, AND NOTHIN COMES ON MY MONITOR.! I TOOK EVERYTHING OUT, I CLEANED IT ALL AND TESTED EVRYTHING ON TO ANOTHER COMPUTER, AND THEY ALL WORK FINE, INCLUDING THE PCU! I TRIED TO C IF COMPUTER TURNED ON WITHOUT THE HARDDRIVE, DVD RW AND THE FLOPPY DRIVE AND IT DID THE SAME (WICTH I EXSPECTED). THE ONLY THING I DIDNT TEST WAS THE MOTHERBOARD.. COULD THIS BE FAULTY? WILL THIS MEAN TO BUY A NEW ONE OR IS THERE SOMETHING I CAN DO...
P4 1.80GB CPU
P4 MOTHERBOARD
256MB RAM
40GB HARDDRIVE
DVD RW

CAN ANYONE HELP PLEASE, THANKS........ NATHAN .............

If all the other hardware checks out on other computers than all that's left is the Motherboard.

Did you test out the PSU?

Otherwise it sounds like a gone board. You can try clearing the CMOS just for the why not.
