First, the boot does not show due to the main board reasons, this failure is generally due to the main board damage or by the CIH virus damage BIOS. Generally BIOS is lost after the virus is damaged, it will be lost, and it is possible to determine whether the BIOS is destroyed by detecting the hard disk data. There are two reasons to cause this phenomenon: 1. Because of the motherboard expansion slot or expansion card There is a problem, causing the motherboard without a response without plugging in an extension card such as a sound card. 2. For the current-free jumper motherboard, if the CPU frequency set in the CMOS is not correct, it may also be triggered without a fault, and this, as long as the CMOS is removed, it can be solved. Clearing the CMOS jumper is generally near the main board's lithium battery, its default location is generally 1, 2 short circuit, as long as it is changed to 2, 3 short circuits can solve the problem, for the previous old motherboard if the user is not available To this jumper, as long as the battery is removed, when the battery is turned off and then shuts down, then shuts down, and the battery is also reached on the power of the CMOS discharge. For the failure of the motherboard BIOS, we can plug in the ISA graphics card. If there is no boot screen, you can do an automatic update of the BIOS, re-refresh the BIOS, but some motherboard BIOS is destroyed, the floppy drive I don't work at all (according to what I know, the main board of the lagu is like this), at this time, try to solve the hot-swappable method, but according to my personal experience, it can also cause the motherboard to use hot-in-use BIOS. The partial component is damaged, so a reliable method is to write the BIOS update file into the BIOS (the location of the mobile phone) is used with a writer. For the damaged failure of the motherboard, some may be because the motherboard is used for a long time, the battery is made of the circuit board mold (for the previous old motherboard), so that the main board does not work properly, and we can thoroughly clean it for it. Solving the problem, this method also has a wonderful root of the contact of the various slots of the motherboard. Cleaning method: Unplug the BIOS, CMOS battery on the motherboard with the tool, then use a hard brush, washing powder, and thoroughly clean it, and finally rinse it with tap water. After the motherboard is free, try again (the author used this rule of law It is better than a few motherboards and no sequelae is found. Second, the motherboard COM port or parallel port, this fault in the IDE mouth is generally due to the user's charging plug-of-related hardware, at which time the user can use multi-function card to replace, but before replacing the COM bringing on the motherboard The mouth and parallel port (some motherboards can be prohibited normally). Third, CMOS settings cannot save such faults is generally due to the lack of battery voltage, but it can be replaced, but some of the motherboard battery is also unable to solve the problem, there are two possibilities: 1, motherboard circuit issues, For this, you must find a professional maintenance; 2, the motherboard CMOS jumper problem, some because people are faulty, set the CMOS jumper on the motherboard to clear options, so that CMOS data cannot be saved. Fourth, the phenomenon of crash or optical drive reading speed slower after Windows and the motherboard driver has encountered such a phenomenon in some non-branded motherboards, and after the motherboard driver is installed, restart the computer cannot be Enter the WIN98 desktop in normal mode, and the driver cannot be uninstalled under Windows 98, and the user has to re-install the system. In some magazines, it is possible to improve some articles in the host speed, enhance system stability, but in the five-year computer maintenance experience, it has never felt this, with my personal experience. In terms of devices conflict in Win98, there is no need to install the motherboard driver.
