Such failures are generally due to insufficient battery voltage of motherboard, which can be replaced to solve the problem, but some motherboards can not solve the same problem after changing the battery, then there are two possibilities:
1. Motherboard circuit problems, which should look for professional service;
2. Motherboard CMOS jumper problem, Sometimes because of incorrectly set the CMOS jumper on the motherboard clear option, or set to an external battery, making CMOS data can not be saved.
Fault 3: In Windows, after installing the motherboard CD-ROM driver, cause the phenomenon of crash or slow down read the disks.
In some no-name motherboard can sometimes be such a phenomenon. After installing the motherboard drivers, restart the computer can not enter the Windows 98 desktop, and that the driver under Windows 98 can not be uninstalled. If this occurs, it is recommended to re-find the latest drivers and installed, the problem can be solved generally, if it is not, can only re-install the system..
Fault 4: When installing Windows, or start the Windows mouse is not available
Reason for this failure of the software is generally caused due CMOS settings wrong. Power management settings in the CMOS field has a modem use IRQ project, his options were 3,4,5…, NA, generally it’s the default option is 3, set it to 3 items can break away.
Fault 5: Frequent computer crashes, freezes occur during the CMOS settings.
Phenomenon occurred in crashes in the CMOS, usually the motherboard or CPU problem, should the failure by the following method does not resolve, it can only replace the motherboard or CPU.
This failure was due to board Cache general problems or bad motherboard design heat, I had already found because of cooling is not good enough to result in the failure phenomenon in the 815EP motherboard. After the Death Touch CPU motherboard components around, and found that the temperature is very hot. After replacing the high-power fans, crash failures can be resolved. Cache problems for failure, we can enter the CMOS settings, you can be successful after the Cache ban, of course, Cache ban will definitely affect the rate.
Fault 6: board COM port or parallel port, IDE port failure
This failure is usually due to user hot plug related hardware. At this time user can use the multipurpose card to replace. However before replace must be prohibited the COM port and the parallel port on the motherboard (some motherboards with IDE port to be banned for proper use).
