How to solve the boot CPU fan error?

When the CPU fan error on the boot is the CPU fan errors. This is when the system detects a problem with the CPU fan or does not detect the fan speed at all, so it is blocked from entering the system for security reasons. "Fan speed" This parameter is very important, the computer and system to control it to the computer for the cooling, if it can not control it, may cause many problems, serious may cause the system to shut down the machine or even the CPU temperature too high to burn the CPU and other hardware

Suggest that you must solve this problem as soon as possible, the problem should not be a long time before the boot. You can open the chassis cover to see if the fan can be normal rotation, if not normal, please immediately shut down and replace the fan, if it is normal rotation, it is your system or BIOS information error, recommend the replacement system ...

1, first check the fan has been dust and other things blocked the speed of abnormal. There is the clear.

2, check the CPU fan wiring is correct. General motherboard does not detect the CPU fan and the motherboard is set up self-protection will be prompted. will be right anyway and position.

3. Fan speed is not enough. Order some lube and don't be too careful.

4, not good words to change a fan bar, but do not recommend the BIOS in the alarm removed.

Use MHDD software to detect the bad way to repair a hard drive:

In the maintenance of a large number of bad hard drive found alone with the PC 3 000 repair bad way, with MHDD scan or have a lot of bad left behind, need to cooperate with other software operation, can really repair bad way (including genuine PC3 000 also the same). MHDD is a green free detection and repair tool, can effectively detect the hard drive bad road situation, so as to repair, the software itself is only more than 100 k, but the function is not unambiguous.

MHDD can access the IDE port directly without relying on the motherboard BIOS and can visit 128G of oversized hard disks (accessible sectors ranging from 512 to 137438953472), even if you are using 286 PCs, without BIOS support, There is no need for any interruption support. Hot-swappable order to remember: when inserting, first plug the data line, and then plug in the power cord. Unplug the power cord, and then unplug the data cable.
