5 If the memory module in the computer case is dusty, disassemble the case, remove the memory module, clean the memory gold finger, and reinstall it.

6. If the memory of the computer is bad for a long time, the parallel memory is bought, and the multiple memories are incompatible when used together, etc., it is recommended to replace the memory to solve the problem.

7 The computer has been used for a long time, the hard disk is broken, and the logical bad sectors can be repaired by repartitioning and installing the system, but it still doesn't work, then it's time to change the hard disk, and it can be solved by changing the hard disk.

Note: If it is a software problem: the simplest, direct, thorough, effective and fast way is to reinstall the system. (Of course, some people may think that it is the most irresponsible statement, and the machine that has actually been used for a long time should have redone the system).

If there is a problem with the hardware, if you are not professional, it is recommended to take it to a computer store to test, and then change it after the test is good.

Restart the computer, if you can't re-trap Changnian newly install the system, if you still don't Xun Qingxing check the memory and use the eraser to wipe the memory gold finger and clean the memory slot and check the hard disk.

Due to the lack of power to the computer for a long time, it may cause a short circuit in many places on the motherboard, first unplug the power supply and then remove the CMOS battery, and the non-stop jog switch will discharge the motherboard early, and then clean up the dust in the main chassis after Zen imitation, and you can also dry the host if the weather is good.

Hard Disk Detection Failed:

1) SATA wire is not of good quality or is not well plugged in.

Solution: Change the SATA cable or plug the SATA cable into another SATA slot on the motherboard.

2) The hard drive is faulty and may need to be replaced.

3) The BIOS setting is wrong, go to the BIOS to find the BOOT option, and check whether the hard disk is blocked.

4) Try to set the hard disk to boot (whether it is set incorrectly).

I personally recommend that you replace the motherboard battery, there is a sale in the computer city, the price is 10 yuan, after the change, boot into the BIOS, restore the factory settings, press F10 to save and exit.

You can turn off the power first, open the computer case, dial out the memory module, use the eraser to wipe the part of the gold finger (that is, the place where there is a copper sheet) back and forth a few times, and then insert a memory slot back in, and you're good to go. If you don't turn on the computer after doing this, you have to check the graphics card, explain that it is a problem with the graphics card, and you can do it in the same way as above.

Press F10 to save and exit to see if you can enter the system, if not, check whether the hard disk is recognized in the BIOS, and then check the connection status of the hard disk in the main chassis. If you still can't solve the problem, consider reinstalling the system.
