What happens when the computer doesn t turn on? Bonus points for problem solving

There are many reasons for the blue screen, there are software problems and hardware problems, if you have the ability to do it yourself, take the chassis apart, see if the lights on the motherboard are on after powering on, and then see if the CPU fan and graphics card fan are running normally, whether the memory module slot is clean or not, how the hard disk is connected, whether there are bad sectors, it is recommended that you can buy a PC diagnostic card, you can analyze the cause of the computer failure from **.

You first check the operation of each part of the computer according to the system I said, which can not only improve your own level, but also help you analyze and solve any problems.

This is too complicated, there are many kinds of phenomena, if you can remember the blue screen error message, it will be easier to deal with a little, and now the situation is not very easy to fix, you open the case to see if the CPU wind fan is turning, and then look at the memory, whether there is a problem with the graphics card or something, whether the tube on the motherboard is burned out, (such as turning black or, there is a smell of burning, or the capacitor is out of ancient deformation.) It is best to take it to a professional shop to get it repaired.

Most of them are memory or graphics card issues, since yours has an integrated graphics card, then you can try to reseat the memory module a few times, or replace a memory module.

Most of the blue screens are problems with the graphics card and memory modules, and viruses are not ruled out.

You plug and unplug the graphics card a few times, and clean up the graphics card slot and memory card slot.

If it doesn't work yet.

Let's change the graphics card.

It feels like there's definitely something wrong with the graphics card.

Wipe the graphics card or it's the system.

The graphics card is also tried in the same way as the memory.

I've solved it, and the problem is the same. Clean up the dust!

Remember to give extra points.

Type 1: Restart the computer The memory module self-test may not be due to a faulty line, static electricity or something like that, or a loose memory module. So restart the computer and see if it can start the second time, restart steps: long press the power button for more than 5 seconds.

The second way: disassemble the cover, remove the memory module, clean it and then install it If you can't turn on the computer after trying to restart it several times, then you should consider this situation, disassemble the computer, and then remove the memory module.

The third option: If neither of the above two can be opened, then you should consider trying to change a memory module, and you can consider borrowing one.

Here's how:

1. Check whether the power socket and power cord are current, whether the power socket is loose, and whether the connection between the motherboard and the power supply is loose.

2. For the computer that has not been turned on for a long time and cannot be turned on, then check whether there is a large amount of dust in the chassis and remove the dust in the chassis.

3. Dust the graphics card, memory and other accessories in the case, and replace the fan with a new fan if it is seriously worn or broken, and then reinstall it.

4. Check whether the memory module on the computer is loose, and plug it back in if it is loose.

5. Open the computer case to check whether the battery on the computer motherboard is still powered, if there is no power, replace the battery.

Desktop computer won't turn on solution:

1. If there is no problem with the computer line connection, we will first use the simplest method to release the battery electrostatic method to try to solve the problem that the computer cannot be turned on. Unplug the console, and then press the console power on button a few times.

2. If you still can't turn on the machine, we need to enter the disassembly process, open the case panel, find the BIOS battery on the motherboard, cancel it and let it contact the metal for a few minutes before installing it back.

3. Of course, the reason why the computer can't turn on is not only the battery, but also the memory module, graphics card, and CPU are suspicious.

4. The CPU is too precise, and it still doesn't move. Remove the memory module first, (be careful not to pull it out, break the buckles on both sides and take it out) and wipe the gold finger with an eraser. Reassemble.

5. Next, also remove the graphics card and wipe the gold finger part. Put it back on and restart your computer.

6. Of course, dust is also a big killer that causes the computer to not turn on, if there is too much dust, it should be cleaned to avoid short circuit on the motherboard.

When the computer can't turn on, try to clean up the dust inside the case, dust is the biggest killer of the computer, too much dust may cause the computer to crash frequently, and in serious cases, it may short-circuit the circuit, and then damage the computer.

Replug the hardware inside the computer case, especially the memory module, remove it, use an eraser or soft cleaning paper to remove the oxidizing material on the surface of the gold finger, and thoroughly clean the dust in the slot before reinstalling it, and then try to boot it again.

Open the back cover of the case, remove the motherboard battery, discharge the battery to restore factory settings, and try to turn on the computer again after the above operations, and it will boot up successfully under normal circumstances.

If it still can't be turned on, it is likely to be a hardware failure, and it is recommended to go to a local computer store for testing and repair.

In fact, there are many reasons why it can't be turned on, such as no power and memory sticks, which need to be checked one by one, if there are no problems, you need to take it to the repair shop to check.

It is recommended to reinstall the system.

There are many reasons for the failure of a computer black screen, such as a damaged monitor, a damaged motherboard, a damaged graphics card, a poor contact of the graphics card, a damaged power supply, a damaged CPU, etc. For the treatment of the black screen of the computer, the method of eliminating and replacing is basically adopted, and the principle should be based on replacing and eliminating the most suspicious parts first.

1.Unplug the data cable connected to the monitor and the console, and turn on the power switch of the monitor separately. Generally, if the display is normal, it will display the manufacturer's information of the display or a prompt that the monitor is not connected, if it can be displayed normally, it indicates that the display is unlikely to be damaged.

2.Check that the exposure is good. Check whether the contact between the graphics card and the monitor is good, and whether the contact between the graphics card and the motherboard IO slot is good, and if necessary, remove it and reinstall it again to ensure that it is installed in place and in good contact.

3.If there is no problem with the monitor, check whether the CPU fan is running, if it is running, use a multimeter to measure whether the voltage output is normal to 12V, 15V, if not, you can change the power supply to give it a try.

4.If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory sticks, and the cause of the fault can be limited to the CPU, motherboard, and memory. Generally, if there is a fault in the memory, there should be an alarm sound.

If the memory fault is ruled out, only the CPU and the motherboard are left.

I know you're looking for someone else to help you miserable.
