Troubleshooting computer motherboard BIOS Frequent reset

Some use a bit longer computer, their own motherboard is always the problem of BIOS reset, the motherboard has overclocking set, all lost, the processor back to the default frequency. Many users will think that the motherboard battery is dead, sometimes replaced the battery failure is still, we may wish to use the following steps to see what is the failure caused by the motherboard is often the problem of the BIOS reset.

The battery on the motherboard does not power, causing BIOS information to not be saved

1. Check jumper

The motherboard is designed to empty the CMOS content of the jumper, if the jumper plug wrong, or jumper cap off, then the BIOS can not save, each boot will be emptied once. So first we let the user to the motherboard instructions, found the location of the jumper, but found that the jumper cap correctly placed here, obviously the problem is not here.

The empty jumper is usually located near the battery

2. Detect Shrapnel

Although the user has replaced the new battery, can not be the battery base does not, cause the battery can not power to the motherboard? We let the user carefully examine the battery seat on the motherboard, especially the shrapnel at the bottom. The shrapnel is resilient and can be well contacted with the battery, which is not the cause of the problem.

3. Electrostatic interference

Is it possible that the motherboard has accumulated a large amount of static electricity, causing interference to the motherboard line? We let the user find a wire, tied to the chassis on the ground, to release static electricity, but still no effect.

4, check the motherboard is leakage

Motherboard startup, daily use everything is normal, so the motherboard failure this piece we do not consider for the time being. User's motherboard has been used for many years, will some components have leakage of the situation? For this reason we recommend that the user will be removed from the motherboard, in the following screw installation hole position on some insulating rubber mat. This solves the problem, and the BIOS can finally save the information.

BIOS cannot save information this phenomenon in some use longer motherboard is more common, cause this kind of fault more, if according to our above method, can not solve the problem, it may be the motherboard South Bridge damage, can find maintenance personnel with hot air gun for heat treatment.
