The computer boot monitor does not respond to boot up and does not turn on 20

Is the keyboard light off? The PS excuse you use for the keyboard is still the USP interface,If the USP interface you use doesn't light up when you just boot up, it's normal,The boot display doesn't light up,If there are 2 reasons according to what I met,One is that the graphics card is loose,The other is that the graphics card is burned out when you hot-swap it。 You turn it off again, simply unplug the graphics card and try to see if it can turn it on.

Because every machine has an integrated graphics card, you don't have to worry about the problem that it can't be displayed without a graphics card. Let's talk about new developments.

Happy New Year, friends!

See here's how to restore your system:

After the computer is turned on, press the "one-key rescue" shortcut key on the far right of the keyboard (the "+" sign on the keypad), and then wait for the "deep one-click restore", wait for the system to "rescue and copy" all disk files, and finally "enter the main platform", and the computer will immediately return to the factory state!

It could be that the graphics card slot is not in good contact. Our family was like this some time ago.

Dizzy, it's broken, I haven't heard that graphics cards support hot swapping! Ha ha.

A reboot will be fine.

1. Computer boot failure: the host can start when the desktop computer is turned on, but the display screen does not respond.

When the desktop computer is turned on, the host can start but the display screen does not respond, in addition to the problem of excluding the connection cable, the main reason is: the computer is used for too long, the gold finger of the memory card and the graphics card is oxidized by the oxygen in the air, and covered with a film of metal oxide, which leads to poor contact, and the computer host can start, but the display screen does not respond to the fault.

Solution: 1. Check the cables between the monitor and the host and the monitor and the power supply, and remove all the cables behind the host and open the side cover of the chassis after confirming that there is no problem.

2. Remove the memory and graphics card from the motherboard of the computer.

When taking the memory, break the buckle of the memory to both sides, and then pull the memory up;

3. When taking the graphics card, first unscrew the gong nails installed on the back of the graphics card, unplug the power cord of the graphics card, and then pull the graphics card up (note that there is also a card on the right side of the graphics card);

4. Clean the slots of memory and graphics card with a small amount of anhydrous alcohol (containing ethanol), leave it for a while or dry it with a hair dryer;

5. Use the eraser to erase the gold finger of the memory and graphics card;

6. Install memory. When installing the memory, align the slot and press down firmly until the memory fastener automatically returns to its original shape.

By increasing the contact area between the CPU and the heat sink, the heat conduction effect is improved, and the CPU is not damaged due to the high temperature of the CPU. However, it should be noted that because the thermal conductivity of metal heat sinks is much stronger than that of thermal grease, the use of thermal grease here is only used to fill the gaps, not to connect the CPU and heat sinks.

When encountering this situation, you can first check whether the computer has been connected several cables, one is the power cord of the monitor, one is the power cord of the computer host, and one is the connection line between the monitor and the host, if one of the three wires is not connected, this phenomenon will occur, and the solution is very simple, that is, the loose wire can be plugged in again.

After eliminating the problem with the power supply and cables, if the fault is still not solved, you need to check it from inside the computer.

1. First of all, you can check whether the power indicator of the display is on, if the power indicator is not on, it should be a fault inside the display, and it needs to be sent to a professional place for maintenance of the LCD screen.

2. If there is no problem with the display itself, then you need to check whether the power supply of the computer host can not be supplied normally, if so, you need to replace the power supply of the computer host in time, and this problem can be solved.

3. There is also a need to check whether the memory module on the computer motherboard is the graphics card is in poor contact, you can now remove the memory module and graphics card, gently wipe the metal sheet on it with a cotton swab, and then plug it back in, and you should be able to start the computer normally.
