6. The motherboard cannot self-test successfully after booting:

1. Press the "Del" key to reset the CMOS or clear the CMOS;

2. Replace the memory module;

3. Re-flash the BIOS or replace the same BIOS chip.

7. After booting up, the motherboard can work normally, and the BIOS detects the keyboard part and reports that the keyboard is wrong?

First of all, see whether the keypad lock is locked, and release the keypad lock. If not, check whether the cable between the motherboard and the backplane and the keyboard and mouse are connected correctly.

8. After booting, other parts work normally, and the reading light of the floppy drive is always on, and the floppy drive cannot be used?

It should be the floppy drive data cable reversed

9. The industrial computer can be started before installing the hard disk, but it cannot be started after installing the hard disk?

Please first check whether the hard disk data cable is reversed

10. Can't use mouse and keyboard?

Check whether there is a keyboard and mouse one-way adapter, and if so, use the keyboard and mouse in reverse.

11. After booting up, the motherboard self-test is successful but the system cannot be booted from the hard disk:

1. Press the "Del" key to enter the CMOS hard disk to see if the parameter setting and boot sequence are correct;

2. After booting with an optical drive or floppy drive, check whether the hard disk has a boot system or whether the hard disk is normally partitioned and the boot partition has been activated.

3. Use the FDISK/MBR command.

12. The memory self-test after booting is inconsistent with the actual capacity:

1. Check whether the motherboard video memory (motherboard integrated graphics card) is shared with the motherboard memory, which will separate a part of the memory as video memory;

2. Check whether the memory is small-particle memory (that is, the capacity of each chip on the memory is less than 16M, for example, the 128M memory should have 8 chips).

Because some old chips do not support large-grain memory, only half of the capacity is displayed after plugging in;

3. A very small number of motherboards use special CPUs, which occupy part of the memory as an instruction decoder for CPU instruction set conversion, resulting in inconsistent memory capacity.
