I have got a massage stated as "warning- processor fan failure detected" at startup. i have checked and found that there was a failure in the fan.so i have replaced it. the fan is working(i can see it is spinning).but i still get the massage.and i cannot access to bios also.because the massage appear after it check the helth and it say helth is ok.by using the normal bios entry is not working(by pressing delete)is there any other way to fix it? i have checked the fan with another comuter and it is working fine. thanks.
When my system had a problem, it was the second fan! My board not only had a processor fan but it also had a very small bios fan. If either fan slows down, the system will shut down. Also, check and make sure that you are using the correct jack for your fan. It sounds dumb but most newer boards has multiple jacks for fans. If you are sure that you are using the correct jack and you are using a fan with 3 wires, not 2 (3 wire fans has a ground, positive 5 volts and a sensor wire to tell the board the speed of the fan) then you have a major problem. Your motherboard has a circuit that is designed to prevent the system from running without proper cooling. Even with a new fan, if the circuit is malfunctioning -- YOUR DONE. Unless your bios gives you the option of bypassing this safety feature, you will need to replace the motherboard which is another bag of worms. Even if you buy the same board and install it, most of the time the system will lock up during boot because of some slight difference in the new board. Sorry for the bad news. Just make sure that you have the 25 digit number for your operating system so that you can reinstall Windows. It should be stuck on the computer case. With that you can replace the board, reinstall Windows and re-register with Microsoft. That way you can download the over 90 updates needed with XP (assuming that you are using XP). Good Luck

I would replace the fan right of the bat, it has a high failure rate, also remove the heatsink to check the thermal grease is not hard, if it is, remove with rubbing alcohol and paper towel along with the processor, then apply fresh compound to both and assemble.

I supose the fan works, you then need to enter bios and disable cpu fan monitoring, if the fan doesnt spin connect it to another fan connector or a plain 4pin molex connector / might require a adapter.
Try to get into bios and disable cpu fan fail alarm, keep the temperature alarm on 80 or 70. so it will yell if it gets too hot.
