IF IT HAS A DOOR FOR ICE CHECK TO SEE IF IT IS CLOSING , REMOVE LIGHT BULBS, OR YOU CAN TOUCH IT (NASTY HOT WARNING) WHEN FIRST OPENING THE DOOR.. MAKE SURE THE FAN WORKS IN THE FREEZER (OIL IT WITH LIGHT OIL) "ZOOM SPOUT OIL". RECOMMENDED.. ALL WORKING NOW . DEFROST IT USE A FAN TO SPEED THE PROCESS, TAKES ABOUT A HOUR. WIPE INTERIOR DRY .. TRY IT AGAIN .. BEST OF LUCK.. JAY

Replace the RAM on other slot and check.
Remove CMOS cell and check.
Finally, change the powersupply and check, it could be due to powersupply not producing enough power.

if only processor fan is moving & there is no any other processing like ram beep etc then check your processor & motherboard.
if you have any other board with same conf. then interchange the processor & check.

belt off or worn

Did you swap RAM and CMOS from other PC? Try to swap the Power Supply, and the motherboard as well, make sure that these 5 parts are in good condition, 1. motherboard 2. powersupply 3. memory(ram) 4.Display adapters/onboard VGA 5. Monitor

onboard video chip is known to be faulty 90% of the time, get an add-in card replacement: http://www.newegg.com/Product/Product.aspx?Item=N82E16814161011

i have longer induction , problem is EO error on the display..
i changed(IGBT,Fuse,Capasiter) what i do?

Try pushing it back in, making sure that it clips into place. You might have shorted out your motherboard though when you moved the pc into the other room. Are you getting power to the powersupply, ie - can you hear or see the powersupply fan spinning? If the power supply is not going on, you may just need a nore powersupply. I hope that helps.

make sure the fan motors are running. there is one near the compressor in the bottom rear and one in the freezer area. also be sure the compressor is running. being it was in storage there could be rust on the motors or possibly a mouse could have chewed through some wires.
