Anonymous users2024-02-07Hello friends, you can troubleshoot from the following aspects: 1. First of all, consider the power supply problem, whether the power supply is insufficient, such as changing the graphics card? cpu？
In addition, the aging of the power supply will also cause the unstable power supply to cause the system to be unstable, the easiest way is to borrow a 300W power supply to try. Second, secondly, consider whether the gold finger of the memory graphics card is oxidized, and use an eraser to erase the gold finger on it before installing it. Third, finally consider the motherboard problem, usually the motherboard capacitor burst will also appear like this, you carefully check all the capacitors on the power supply, especially a few large capacitors around the CPU, whether there is a bulging phenomenon, if there is, it is recommended to send it for repair or have strong hands-on ability to buy a matching capacitor to weld it on.

Anonymous users2024-02-06The black screen of the computer does not show anything, which is generally a hardware failure. Software glitches usually freeze, mouse and keyboard don't respond, or blue screen. According to the problem you reflected, the focus is to check two places, one is the memory module, turn off the power, turn on the compartment, remove the memory module and plug it back in; The second is to check whether the graphics card is loose, unplug the graphics card, plug it back in, and then turn on the power supply and start the system.
Also, you check if the case and the monitor are connected, maybe the interface from the graphics card to the monitor is loose.

Anonymous users2024-02-05The computer suddenly went black, and it couldn't be turned on again.
Resolution. 1. Release static electricity 1. When there is a problem that the machine cannot be turned on, we can first use the method of discharging static electricity. The specific operation method is to turn off the power of the host first, and then press the power switch of the host several times.
2. If the above method doesn't work, we can also try to open the host panel. Before operating, disconnect the main unit from power. Find a button-sized piece on the motherboard, and it's the BIOS battery.
In the outer ring of the battery there is usually a spring for fixing, and the battery can be removed by pressing and holding. 3. Manually deduct the BIOS battery from the motherboard and put it back in after a few minutes. After restoring the BIOS battery, plug in the console and see if it can turn on properly.
Resolution. Second, plugging in the memory 1, if the above release static electricity can not solve the problem, then we can play the memory attention. In many cases, the computer does not turn on properly, which is caused by poor contact with the memory. The specific reason for poor contact may be that it is shaken loose, or the interface is oxidized over time.
At this time, please disconnect the power supply of the host and open the host panel, find the rectangular memory module 2 on the main card, remove the memory module on the motherboard, and then turn on the computer to see if the host will have a beep alarm. If there is, then it must be a memory problem.

Anonymous users2024-02-04Summary. Step 1: When there is a problem that the machine cannot be turned on, we can first adopt the method of discharging static electricity. The specific operation method is to turn off the power of the host first, and then press the power switch of the host several times. Step 2: If the above method doesn't work, we can also try to open the host panel.
Before operating, disconnect the main unit from power. Find a button-sized piece on the motherboard, and it's the BIOS battery.

Step 3: Manually remove the [BIOS] battery from the motherboard and put it back in a few minutes.
After restoring the BIOS battery, plug in the console and see if it can turn on properly. The computer suddenly has a black screen, and it can be operated like this if it can't be turned on again.
The computer suddenly went black, and it couldn't be turned on again.
Hello, according to the problem you described. The computer suddenly went black, and it couldn't be turned on again.
I'm sorry I don't understand, but can you elaborate on that?

The computer suddenly went black, and I couldn't open it anymore, hello! 1. The boot display screen is black, only the indicator light is on, and the host does not have any reaction. Stretching out the back of the host unit does not feel the fan turning, and there is no voltage for all channels.
Remove the power adjustment tube and replace it. 2. When the computer is turned on, a long alarm will be heard, which should be a memory failure. You need to unplug the memory, clean up the gold finger, and then insert the memory module normally.
3. The power supply and CPU fan are normal, but the computer screen does not reflect anything, and there is no self-test sound. If the computer uses a slot1 structure, the CPU is prone to poor contact, so you can reinstall it. 4. The self-test is normal, but the computer screen is not lit.
It may be that there is a problem with the display cable that connects to the computer screen. Unplug it and take a look, sometimes there may be looseness, just reconnect. 5. The computer has a black screen when it is turned on, and the machine does not self-test.
Apply the watch pin to short the boot terminal on the motherboard, and then boot normally. Sometimes the start switch on the panel will be damaged, and it can be replaced. Hope it helps!

Anonymous users2024-02-02Summary. First of all, it is necessary to determine whether the computer can be powered on, if it cannot be powered on, it is likely that there is a problem with the power supply, now the computer generally uses a standard ATX power supply, if there is a problem with the power supply, then the computer must not turn on, and it can be replaced with a new ATX power supply. Second, make sure that there is no problem with the power supply, but press the switch of the computer still does not respond, it may be that the motherboard is faulty, at this time you need to send the motherboard to a professional maintenance organization for inspection.
3. If the computer can be powered on, but the computer screen is black and does not respond, it may be that there is a problem with the motherboard or memory, graphics card and other accessories, causing the computer to fail to turn on. You can use the motherboard diagnostic card to plug it into the PCI slot of the computer motherboard, and then press the switch to see what is displayed on the diagnostic card**.

Can you tell us more about that?
1.If it is FF or 00**, there may be a problem with the motherboard or CPU; 2.If there is a code such as D3 and C1, it is generally a problem with the memory module, you can use an eraser to erase the gold finger of the memory, and try again, because the memory is in long-term use, it may cause the gold finger to oxidize due to moisture, and the contact with the motherboard is not good, which causes failure; 3.
If it shows 2A but the screen is not yet displayed, it may be that the computer cannot be turned on due to a problem with the graphics card. If the cleanup doesn't work, find a good graphics card to find the problem using the elimination method. Fourth, if according to the above method of processing, the computer still can not turn on, then the problem is more serious, it is recommended to send the computer to a professional maintenance point, let professional technicians check and process, ordinary users do not believe in Qin to repair at will, otherwise the fault may be expanded, the gains outweigh the losses.
