that is problem of processor when processor is overheated it do so there is a white heat sink compound between processor and heatsink detach heat sink and apply new heat sink compound on the processor and look properly that heatsink is firmly fixed to processor or not .it may problem of fan if fan is rotating with low frequency then also it happens replace new fan the frequency of fan can be seen in setup
Usually, there are two fans on a desktop PC. Some computer have three.
One cools down the power supply and it may be quite noisy after a while because the dust in the fan. The second one is to cool down the processor and usually it doesn't stops, it only changes its speed according the heat.
If there is a third one, it will stop when the temperature is cool enough for the system.
Only on notebooks the processor fan stops completely after a while to save some energy.
when the fan stops 2 things are happening 1 the bios sences no rpm speed from the fan or the processor heats up to quickly and the safety in the bios will shut it down. try moving the fan connector to the case fan connector then go into the bios and change the fan settings. this is only a temp fix the fan stopping tells me that the onboard cpu fan regulator is going out and this is a precurser to more problems to the board going out. also just to be certin check the power supply 4 years ago i came across this in a gateway it was weird.
IF I UNDERSTAND WHAT YOU ARE TRYING TO SAY I BELIEVE I UNDERSTAND MOST ENOUGH TO SAY YOU HAVE VERY SERIOUS PROBLEM AND NEED TO STOP EVERYTHING RIGHT NOW UNTIL YOU FIX CPU!! YOU HAVE SERIOUS OVERHEATING PROBLEM AND ARE PROBABLY CLOSE TO KILLING YOUR WHOLE SYSTEM!! A PENTIUM 4,3GHZ PROCESSOR PUTS OUT A LOT OF HEAT AND THAT IS WHY THE HEAT SINK MELTED, BUT YOU CAN'T RUN WITHOUT REPLACING IT WITH SOMETHING ELSE BETTER THAN WHAT YOU HAD THAT DIDN'T WORK! THIS IS WHY THE WHOLE SYSTEM IS SHUTTING DOWN. IT IS SAYING, IT IS WAY TO HOT TO RUN AND WE ARE GOING TO SHUT DOWN BEFORE WE BURN UP!!! YOU MUST GET MORE COOLING INTO YOUR CASE AND ONTO THAT PENTIUM PROCESSOR AND GET MORE HEAT OUT OF THE CASE. YOU MAY NEED TO ADD ADDITIONAL FANS OR VENTS, BUT YOU HAVE TO REPAIR THE DAMAGE BEFORE YOU RUN THIS MACHINE OR YOU WILL FRY IT!! THE MOTHERBOARD CAN'T TAKE THE HEAT EITHER! REPLACE THE HEATSINK WITH AN ALUMINUM ONE, NOT THAT PLASTIC ONE FROM DELL, AND MOUNT A FAN ON TOP IF NEED BE. YOU HAVE TO THINK COOOOL!!! YOU HAVE THE POWER, BUT IT ISN'T GOING TO DO YOU ANY GOOD IF IT GOES UP IN SMOKE! I'VE BUILT TO MANY MACHINES TO SEE ONE FRY FOR OVERHEATING. YOU SHOULD HAVE AT LEAST FOUR FANS IN THAT CASE, NO COUNTING THE ONE ONE THE VIDEO CARD OR THE ONE IN THE POWER SUPPLY. DO IT RIGHT AND SHE WILL LOVE YOU FOR IT AND PURR LIKE A KITTEN!

The surge probably didn't cause this.
This common error indicates a problem in the convection damper circuit.
It may be a defective damper switch, damper motor, or a jammed damper door.
I have attached a drawing of a typical damper system.
