Black screen of death, can t turn off and turn off the monitor, can only restart!

Since you're sure that the hardware is fine, the problem may be in terms of heat dissipation.

If the CPU fan is not in good contact, the heat dissipation efficiency will be reduced and the CPU will crash. Just apply a little silicone grease and you're good to go. Silicone cannot be used. Don't buy it wrong. Silicone grease 2 yuan 1 bottle. Apply a thin layer.

The same goes for graphics card fans, which are generally prone to problems. See if the speed is fast

If it's hardware such as memory, the hard drive will have a blue screen. So ruled out ...

If the power supply is not enough, it will be extremely unstable. It doesn't even turn on. You've only been like this lately, so the power supply is fine.

In terms of software, you reinstall the system to see. Then use the test software everest to see if the temperature of each of your accessories is normal.

The Leadtek FX 540 professional graphics card is not the same as a gaming graphics card, they are superior in other aspects such as graphics, animation, or workstations. The game graphics card is generally around 1000, which is very good. You use this graphics card a lot for animation.。。

It can't be a virus! Wasn't that the case before? The monitor won't turn off, that's a bit unlikely!

The crash is generally due to poor CPU heat dissipation, and there will be a blue screen! Your CPU memory should be fine!

Check your graphics card more.

It's your monitor's problem. Does the computer work properly after the black screen, but the screen goes black?

There may be a problem with the cable connecting the monitor to the computer.

If you suddenly can't turn on the black screen, this is likely to be four reasons:

The first reason: due to the memory or graphics card's gold finger is oxidized, resulting in poor contact between the memory and the memory slot, the poor contact between the graphics card and the graphics card slot, and the inability to turn on, the screen will naturally be black, the treatment method: turn off the power, open the chassis, remove the memory and the independent graphics card, use the eraser to align the gold finger of the memory (that is, the part with the copper sheet) on both sides of the wipe a few times, and then insert them back, the independent graphics card is also processed in the same way, and then the chassis is installed, plugged in the wire, generally treated like this, OK, (take the memory diagram as follows:.)

> the second reason: that is, the graphics card's video memory is soldered, the performance of the main chip is reduced, the graphics card BIOS is disordered, and the control power supply IC is problematic, which will cause the graphics card to fail to work normally, that is, the graphics card is broken, and the computer will naturally not be able to display, and the screen will be black when it is turned on.

The third reason: the problem of power supply, when the filter capacitor of the power supply is bulging, leakage, there will be leakage, when the power supply is insufficient after starting, there is not enough voltage and current for the host to start, the power self-protection circuit starts self-protection, power off, no electricity, it is naturally a black screen, the treatment method, which can only replace the power supply.

The fourth reason: if the host is normal, the connection line is also normal, or the black screen, which is the problem of the liquid crystal display, when the power supply circuit, the high-voltage board circuit, the drive board circuit, no matter which link has a problem, such as large filter capacitor bulging, switch tube open, high-voltage package open circuit, lamp damage, MCU chip damage, power supply regulator damage, poor screen cable contact, etc., will make the LCD screen appear black, so at this time, only the display can be repaired. (If within the warranty period and after-sales service).

The fifth reason: that is, there is a problem with the boot circuit of the motherboard, or the CPU power supply is abnormal, the north bridge is damaged, etc., etc., etc., will cause the boot, black screen, and the host does not respond, the solution: is to repair the motherboard, (if it is in the warranty period and after-sales service).

The first of these reasons is the most likely.

This is due to a malfunctioning monitor or a connection issue. Please check that the power of the monitor is turned on normally, if not, you need to check that the power of the monitor is plugged in, and make sure that the power switch of the monitor is turned on. If the issue persists, it may be caused by a signal cable connection issue, make sure it is connected correctly.

If you've checked all of these steps, restarting your PC might resolve the issue, but if this happens frequently, you might need to check further.

It could be that your monitor's high refresh rate is set too high or that there is an issue with your graphics driver. In this case, you can try to update the driver from the official graphics driver, or reduce the refresh rate of your monitor according to your monitor's refresh rate settings. It can also be caused by other hardware failures of the display.

In this case, you may need to replace or repair the hard and discredited parts of the monitor.

If your monitor is malfunctioning, there are also some possible ways to fix it. First, you can try testing your monitor on a different computer to see if it's a hardware issue or a connectivity issue. If it is due to hardware problems, the monitor will have to be replaced.

If it is due to a connection problem, the signal line can also be replaced or the connector replaced.

In conclusion, the cause of your monitor's sudden black screen could be a power issue, a signal cable connection issue, a high refresh rate, a graphics driver issue, or a display hardware failure. To fix this, you can restart your PC and do some hardware checks and try to rule out some troubleshooting to determine what the problem is. If that doesn't work, consider replacing your monitor or seeking professional repair help.

Black screen after the monitor reboot Hello, if your computer has a black screen after restarting, you can try the following actions to solve the problem:1Check that the monitor is working properly:

2.Check your computer's power: Make sure your computer is powered on and that the power cord is connected to your computer and power outlet.

3.Check if your computer will turn on: Press the power button on your computer before trying to keep it up and see if it starts up properly.

If your computer boots up but you still get a black screen, your display may be malfunctioning. 4.Try using an external monitor:

If you have an external monitor, connect it to your computer and see if it works. If you're able to use an external monitor, it's possible that the built-in display is malfunctioning. 5.

Check whether the computer is damaged: If the above steps cannot solve the problem, it may be that the computer itself is damaged, it is recommended to send the computer to a professional repair shop for inspection, I hope mine can help you I wish you good health and a happy mood <>

Hello: If you suddenly can't turn on the black screen, this is likely to be four reasons:

The fourth reason: if the host is normal, the connection line is also normal, or the black screen, which is the problem of the liquid crystal display, when the power supply or flush circuit, high-voltage board circuit, drive board circuit, no matter which stove shirt link has a problem, such as large filter hidden cavity wave capacitor bulging, switch tube break, high-voltage package open circuit, lamp damage, MCU chip damage, power supply regulator damage, poor screen cable contact, etc., will make the LCD screen appear black, so at this time, only repair the display. (If within the warranty period and after-sales service).

The fifth reason: that is, there is a problem with the boot circuit of the motherboard, or the CPU power supply is abnormal, the north bridge is damaged, etc., etc., etc., will cause the boot, black screen, and the host does not respond, the solution: is to repair the motherboard, (if it is in the warranty period and after-sales service).

The first of these reasons is the most likely.

Generally, the restart is caused by your own incorrect operation, remember not to do the operation that is easy to cause the restart. The computer should not operate at full capacity, that is, when playing games, watching **, **, and watching web pages at the same time, it is easiest to restart, freeze, and blue screen, so don't operate other things when playing games, watching**, **, and watching web pages.

In terms of hardware, the temperature of CPU and other hardware is too high, the memory is less than the card, the hard disk is bad, the voltage is unstable, and the hardware is not suitable.

Suggestion: 1. Do not overclock the CPU, graphics card and other accessories, and pay attention to the temperature, otherwise, it will restart or freeze inexplicably when starting or running. When replacing the accessories of the computer, be sure to plug it in, because the poor contact of the accessories will cause the system to crash.

2. BIOS settings should be appropriate, although it is recommended to set BIOS to optimal, but the so-called optimal is not the best, sometimes the optimal settings will cause startup or running crashes.

3. It is best to be equipped with a stabilized power supply to avoid a crash caused by unstable voltage. If possible, install a UPS so that the computer will not crash after a power failure.

4. For floppy disks and CD-ROMs of unknown origin, do not use them easily, and use the software attached to the e-mail with KV300, Rising and other anti-virus software before checking, so as not to imitate the infectious disease or poison the system.

Check first if it's a display problem,The way to check is to unplug the signal cable to see if there is any response,For example, there is no signal and other font display,Excluding the display is an integrated graphics card。

In this case, you can only take it to a professional computer repair shop to see, and the possibility is that the hard disk is broken, the CPU temperature is high, the motherboard is broken, and it is poisoned. Wait a minute...

1.The speaker of the building reserve wood presses the power button to turn off;

2.After rebooting, it is recommended that you can keep clicking the F8 button to select the last correct configuration when HP (or Compaq) appears at boot (or restart).

3.After rebooting, go to the system, set the power usage scheme in the Control Panel - Power Options to High Performance (XP system is always on), and then test. If the problem persists, you can consider updating the latest graphics card driver.

4.If the problem persists, you can adjust it to a dual-screen display mode through the external monitor, and you need to contact the Gold Service Center for on-site confirmation for the specific situation.

a.If the external monitor is displayed normally, it may be related to the local display.

b.If the external monitor is not displayed properly, it may be related to the local graphics card or motherboard.

1. Graphics card memory problems.

Replug it in, clean the gold finger, and see if the fan is normal. Update the driver, you can ** drive the wizard) 2, even the head is not wired problem (replug, check the VGA or DVI connector to pretend to be the socket) 3, the display problem (check whether the power plug is not powered on. If it's convenient, connect it to other computers to see if it's normal).

There are several reasons why the computer monitor suddenly goes black, first see if the power cord is loose, and then see if the cable on the graphics card is loose, and rule out the problem.
