I don't think resetting the BIOS will have the effect you are looking for. Many notebooks hold bios setting differently to a regular PC so removing the bios battery may not work as was suggested. sometimes it requires special procedures and or knowledge to do this with some brands of laptop.

I would suspect that when you cleaned the heat-sink on your CPU you may have accidental forgotten to put new thermal compound on

Whenever a cooler / heat-sink is removed new compound must be put on tho help spread and dissipate heat. Without this there is a chance that the CPU and motherboard could be damaged.

It will do this when it senses that the fan is not working properly or that maybe a setting for the fan is incorrect

First off. If you changed anything using any motherboard / bios utility then change it back or reset defaults.

When you have done that check that the cooling fan / heat-sink for the CPU is secure to the CPU itself (don't remove unless it is loose)

Also check that the fan spins freely.

If it doesn't or feels loose then replace the cooler

Check your manual for the exact instructions but you should remove the cooler completely

DO NOT REMOVE THE CPU

Now with nothing more than isopropynol and cotton bud sticks or another alcohol based cleaner remove the old thermal grease / sticker from the top of the CPU (make sure it is clean)

Do the same with the underside of the cooler.
While the cooler is off it may be worth giving it a good 8low job
.
Now apply some new thermal grease (most computer shops have it)

Be careful about how much you put on
Here are some basic instructions
Once you have re-assembled your cooler and re-connected it check everything is OK and power up the computer.

If everything went to plan and you did not pop the CPU or motherboard you should now be back in business.

Try downloading the latest video driver. it could just be a faulty driver file. Make sure the heatsink is clamped to the CPU correctly. this is much more important than having thermal paste on it. If someone has removed the heatsink, they may not have replaced it correctly

Processor keeps failing


Have you made sure that it cooled properly? That could be one of the problems, as well as some dust between the motherboard and the processor

This sounds like a problem I have just had with one of my PC's.
Try clearing the BIOS using the jumper on the motherboard, if that doesn't work (which it didn't in mine) then you may need to replace the motherboard (which I did).

I was going to say dust is whats causing it but then i relized you have opened your computer. So nevermind that.

The fan speed is controlled by the motherboard. The Pentium 4 processor tells your motherboard how hot it is. so then the motherboard turns up the fan faster. Thats why its louder when the CPU is doing alot and is quieter when its doing nothing. You can try replacing the fan yourself but i would recommend just getting a whole new heatsink.
