Problem 1 New CMOS (Complementary Metal Oxide Semiconductor) settings can not be saved. It is often due to the motherboard battery is turned on, you must change the battery. If the voltage is too low, it may be two possibilities. One, the circuit of the motherboard goes down, and you’d better take it to the pro. Secondly, the problem is in the motherboard CMOS jumper and CMOS sometimes you have cleaned or erroneously described as using the external battery, so it can not save new CMOS data. Problem 2 computer failures or reading CD-ROM slows down after the introduction motherboard drivers. It often occurs in some motherboards below: when you have finished installing the drivers for your motherboard and reboot, you can not get into the Windows 98 interface in normal mode, in addition, the driver can not be unloaded. For that, you’d better find the latest driver for the motherboard and install it if you still have not to reinstall your operating system. Problem 3 mice is not available during installation or startup of your Windows system. It is usually caused by incorrect software settings CMOS. In the power management of the CMOS, there is an element known to use the modem interrupt request, which is commonly the default three, and you can switch to choose one of the other options except 3. Problem 4: Computer crashes when setting the CMOS source of this painful ordeal usually lies in the processor cache, or motherboard, sometimes perhaps the poor heat dissipation in the motherboard gives rise to such accidents. For the cache problem, you can resolve the problem by disabling the cache in the CMOS, but certainly may affect your Internet speed. If this is not the cache problem, no doubt, you should replace your CPU or motherboard. Problem 5 mother COM port, line printer port terminals or Integrated Drive Electronics port does not work correctly. This usually occurs when you hot plug the relevant materials, first you must disable the COM port, the print line of port terminals (sometimes you need to disable port integrated drive electronics) that has built-in the motherboard, then use a multifunction card instead.
