It may be the temperature problem. If the heatsink and the fan does not sit tight on processor the heat from the processor will not be dissipated properly and the heat rises up and the processor shuts off as soon as it starts working. So please see that the heat sink and the fan on the mother board sits tight. Also apply heatsink paste on the surface of the processor which comes in to contact with the heatsink. It comes filled in Syringe and retails around Rs.10-20 only. I think it will solve your shotdown problem.
A pin processor have the pins at its bottom which merges in to the motherboard! A pinless processor has no pins.pinless processor has a flat bottom with around an extra 297 connections to the motherboard. You cant fit one to a pinned socket.vote me if it is helpful
see do one thing check the cpu fan whether it is working properly and is not producing any noise if it is then probably you need to replace your cpu fan with a new one also makke sure that your power supply fan and chasis fan is working as excess heat gets generated in the system they remove it
to change the cpu fan
1.see it will depend on what kind of cpu socket you have pin or pinless
for pin-open the plastic clamp on the fan
for pinless -unscrew the heatsink
2.remove the heatsink and replace it it will be much better if you replace the full heat sink with a new one .also don't forget to put thermal grease compound for effivient heat transfer in between the cpu and the heat sink contact generally these days heat sinks come with pre-applied thermal componds but still it is recomended to apply it firmly over the cpu before installing the heat sink on it
3.if you wish to install the old heatsink by just replacing the top fan then replace the fan and rub the bottom of the heat sink with a sand paper to make it even and free from dust and oxide apply thermal compond and install it on the processor .plug bak the cpu fan header cable .
start your system it will stop overheating..
Processors do not have drivers. They are supported by motherboard chipsets, so you need to make sure you have the correct chipset driver for the operating system you are trying to install. What system brand and model do you have? What operating system?
..plz do check the following as in order:.. the Hardware part:.. 3) unplug mains supply..pick open/remove the cmos battery..check (above +3v)..resit..change if required..
dust neatly..dust is non-uniform in nature n may cause jam/short
circuitry/excess resistance n many more..resulting an increase in heat..
open the CPU Heat-Sink with fan out of the socket..put some "Heat Sink
Compound" (available in local electronics chip level spare market)
between the cpu/processor and the CPU Heat Sink *** fan..resit/fit it
tightly in position..
8)on main/mother board..see with a debug
card for mb error..may bshort..look for defective capacitors(esp
above1000mfd)/mosfets..go through the mb's south bridge n the circuit
lie around atx connector..the crystal clock generator (if cpu isn't
heating up).. if u r not a professional, always better to seek advise from ur system admin/vendor....
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!
