    when i start my computer, i will get two errors:

    Warning: Your Computer CPU Fan Fail or speed too low
    Warning: Your Computer Chip Fan Fail or speed too low

    it says i can simply turn it off, but my computer is running slower than usual so im assuming this is the cause, i have done scans for virus, spyware, vundo, and malware, so this is the only thing i can think could be the problem.

    any help is greatly apreciated.

    Well, have you checked inside the case to see if the CPU fan is too slow? If the CPU is actually slower (less MHz), it most likely is because it is overheating, and it's using its built-in mechanism to save itself by running slower, and therefore not as hot. Make sure the wire going from the CPU fan to the motherboard is plugged in securely, etc. It could be that the fan is getting worn out, and slowing down. If it's plugged into a fan controller, make sure the BIOS option to turn off fan detecting is enabled.

    Open the case and give the system a good cleaning with a can of air [available at walmart, office supply store, etc] Now pw ON the system with the side cover still off. See if all fans in the system are turning.

    Post back with results.

    Only turn off the fan detection if the fan(s) are plugged into an external fan controller, like in the front of the case. But if the fans are plugged into the motherboard, I don't recommend turning off the detection. You may just need to replace the fan that is running slow, assuming it really is running slow. They are not expensive. You might be able to check the speeds of the fans in the BIOS, or by using a free program called Speedfan.
