It s hard to see computer hardware problems, and it s a pity if the experts don t solve them.

Try to replace the motherboard of the bad computer with a good computer, it is best to swap to see what the result is, I think it may be that there is a problem with the components of the regulator part of the motherboard

The power supply capacitors and inductors on the motherboard may be sweating or bursting. It is also possible that the interface connected to the power supply of the motherboard has sweat or desoldering. Take it to the place where the motherboard is overhauled and test it.

This problem is easy to solve, just replace the battery on the motherboard with a new one.

This is due to the storage of electricity from the motherboard battery.

Hello, in fact, your problem has been solved, that is, the failure of the motherboard, the CPU can be interchanged, the problem has been clear (either the motherboard or the CPU), I hope it will help you, I wish you all the best.

The first display does not display most of the problems are memory modules.

Second, the network is not connected, it is recommended to change the network card driver, it is best to reinstall the system quickly.

Thirdly, there may be a problem with the audio chip, or you can update the audio driver to see if you think it's better to reinstall the system.

Fourth, these problems may be that the chip has been used for a long time and is a little bit not working properly, and the dust also affects the gold finger or something like that.

Fifth, if the blue screen is the blue screen that you are talking about, it has the most to do with the memory module, and it is also caused by the command conflict between the software and the system.

If there is any problem with the reinstallation, tell me about it again, if the motherboard detects that the hardware is abnormal, there will be a warning sound, a beep and other sounds, and the law will tell you which hardware cannot be used normally.

F1.

It is very likely that you did not turn off the floppy drive in the BIOS after changing the motherboard battery.

The solution is to boot the computer, enter the BIOS, turn off the floppy drive and boot it.

Time Reset Problem Given that you have just replaced the motherboard battery, there are generally only 2 possibilities.

1 Virus-caused.

2 There is a problem with the circuit of the motherboard battery part.

It is recommended to find a reliable antivirus software to kill the virus.

Suggestion 2: Check the fault of part of the motherboard battery.

Network issues. It may be that the network card, network cable is not in good contact, or there is a virtual connection in the motherboard circuit.

Software issues may be there but may be minor.

Display Questions. 1 may be memory ash.

2. The integrated graphics card circuit of the motherboard has a virtual connection.

3. Insufficient power supply due to aging of power supply.

It is recommended to unplug the memory and carefully clean the gold finger and dust inside the motherboard memory slot.

Then plug the memory back into the motherboard slot.

Suggestion 2: Check some circuits of the motherboard graphics card.

It is recommended to change the power supply three times to test.

Sound problems. 1 sound card driver.

2Contact with the motherboard.

It is recommended to update the sound card driver.

Suggestion 2: Check the connection to the motherboard (the cleaning method is the same as the memory cleaning); If the sound card is integrated, you need to troubleshoot the relevant circuitry.

Given the current state of your computer, the best thing to do is:

1. Reinstall the system and update the driver.

2. Clean the dust from the connections of each part of the motherboard and check the connection status.

3. If the problem cannot be solved after reinstalling the system and cleaning up the dust, it is recommended to replace the 2-hand motherboard of the same model (generally 50 yuan can be bought).

The symptoms you described have nothing to do with the CPU.

If the system cause is ruled out, the main thing is to suspect a problem with the motherboard.

First, the dust has not been cleaned for a long time, resulting in poor contact of the parts.

The second is that the aging of the motherboard is more serious, then you have to replace the motherboard, and generally the integrated motherboard of 2 hands is only a few dozen dollars.

The time you are asking questions here is estimated to be the end of installing a few systems, and you will know what's going on if you install a system.

It looks like it's a motherboard problem.

There could be two possibilities:

1. If there is a problem with the heat dissipation of the main components such as the CPU and graphics card, open the case, start the computer to see if the CPU fan and graphics card fan are rotating, if not, replace the fan with a new one.

2. There is a problem with the hard disk: start the computer with the pirated system disk on the market, start the PE, use the hard disk inspection software to check the bad sectors of the hard disk after entering, if the bad sectors are out of the country, it is necessary to repair them, and it is best to change to a new hard disk.

Another possibility is that you try to change the hard drive cable.

It is recommended to clean the dust first, and then reseat the memory and graphics card.

Have you changed anything recently, such as drivers, or installed any software?

1. Restart the computer, press F8, and the selection menu will appear.

2. Select the last correct configuration, try the safe mode, if you can enter the safe mode, you can uninstall the recently installed software or driver.

3. If this is still the case, you can only redo the system.
