After wiping the dust of the case, the screen will go black when you turn it on, what to do!

If the wires are not plugged in, check the CPU fan, memory, and graphics card. Take these things down and plug them in.

First check the memory and erase the "golden toe" with an eraser.

Let's see if the fan speed of the CPU is enough.

Then see if the thermally conductive silicone between the CPU and the heat sink fails.

The dust in the chassis is best to blow and wipe...

Check whether the memory module and graphics card are loose, it is estimated that it is a memory module

Loose, the gray ticking sound is generally the graphics card or memory is loose, the graphics card or memory slot has dust, pull out the slot, blow out the dust, and replug it in.

The ticking sound after wiping the ash is generally that the memory is loose, or there is dust in the memory slot, pull out the slot, blow out the dust, and replug it in.

As soon as the computer is turned on, the specific reason for the gray screen is to change the source and the solution, the specific situation is as follows:

1. If it is caused by the loose VGA connection of the display.

Solution: You need to connect the host and the monitor.

2. If it is caused by loose or damaged memory modules.

Solution: You can use an eraser to wipe the gold finger of the memory module, reinsert the memory module or replace the memory key module.

3. If it is caused by a short circuit of the host.

Solution: You can try to clean up the host and plug the wiring again.

4. If it is caused by a BIOS problem with the motherboard.

Solution: Try to go to the motherboard BIOS settings page to restore the BIOS to the default value.

5. If you really can't solve it, you need to reinstall the computer system.

If the computer is stuck with a gray screen, under normal circumstances, you can press and hold the key combination, Ctrl+Alt+Tab, enter the task manager, select the corresponding program, select the 'End Application' below, or you can directly press, Ctrl+EAS, and wait for the exit.

Summary. Hello!

1. The computer cannot be turned on due to reinstalling the system. In this case, the computer cannot enter the system normally due to the system not being successfully reinstalled, and at this time, you can remake the boot disk and then reinstall the system by using the one-click reinstallation software.

2. The laptop boot screen is black due to computer content damage or poor contact. This is relatively rare, but if your computer has been in use for a long time, this is more likely to happen, so you can usually try to remove the memory module and try to plug it back in or try to replace it with a different one.

3. The laptop cannot be turned on due to computer hardware problems, and you can usually check whether it is caused by problems such as circuits or monitors. Because the structure of the notebook is more complex, therefore, these problems can not be explained clearly in one or two sentences, if the above two methods are still not well solved, you can try to send the computer to the maintenance process for maintenance.

What to do if your HP laptop is turned on with a gray screen.

Hello, I will continue to serve you <>

You turn it on again, have you ever used a computer before, if you have used it, maybe a hacker has come and left you a summarizer virus, maybe someone else has sent you something and opened it, maybe that's the reason. If I hadn't opened it, I wouldn't know.

I've also encountered this situation, gray screen. There are two scenarios. First, your computer is in the process of booting up, and you may have to wait 2-3 minutes to see the Windows interface. Second, the memory needs to be cleaned up, take out the memory module and wipe it a few more times with an eraser.

Hello, glad to answer for you! This is a system issue! It is possible that the system is poisoned or the system program is broken! It is recommended that you reinstall the system! Hope you help! Give a satisfaction! Thank you!

This is a technique for the display to protect itself. If the monitor is used for a long time, the parts in it are aging or wet, and the display may not be displayed properly due to the failure of the parts when the monitor is displayed.

It is recommended to find someone who repairs electrical appliances to fix it.

There are several reasons for this:

1: Turn on the computer to see if the host power fan is turning.

2: After turning on the CPU, turn on the CPU fan to see if the cable is not plugged in properly, short circuit, turn or can't turn on, it is a motherboard failure.

3: System failure, reinstall the system.

4: The memory is not compatible with the motherboard, and the memory is more.

5: The monitor signal cable is not connected properly.

6: Look at which link the screen is black, see if you have entered the self-test step, that is, to the step where you can enter the coms setting, if you can't get it, the power failure or the motherboard battery voltage is not enough, replace the power supply or motherboard battery.

7: The graphics card is faulty, if it is an integrated motherboard, it is a video memory problem, if it is independent, then replace the graphics card.

Start slowly, wait again, and redo if it doesn't work.

Hello: The most direct reason for the gray screen is the loss of system files, as well as software conflicts, hardware problems, graphics card problems, and display problems.

The principle of solving the software first and then looking at the hardware: system restoration to see if there is a gray screen phenomenon 1: win7, Vista needs the system's own restoration function to boot F11 - advanced - to restore the system to a certain time in the past, that is, the day before and the first few days of this problem, you can do it in a few minutes.

No other approach will solve your problem at its root.

2: You can also boot the computer and press {F8 to enter safe mode} to select System Restore.

3: It is recommended to boot the welcome screen - {F8 into safe mode} to restore, because in the safe mode do not start the software other than the system, if it is fast, it can be done in a few minutes, 4: If it is XP boot F8 choose the last correct configuration, go and try it.

Fix the system, if it doesn't work, use the computer manager to update the graphics card driver, and if it doesn't work, it may be a hardware problem.

1. Press F8 to press F8 to get the advanced option to appear in the release of the power, and select "The latest correct configuration" Enter to repair.

2. Press F8 to enter the safe mode after booting up, and then exit, select Restart or Shut Down to boot on, and you can enter the normal mode (repair the registry).

3. If the fault persists, please use the system restore that comes with the system to restore it to the time when you did not have this failure (or use the restoration software to restore the system).

4. If the fault persists, use the system disk to repair it, open the command prompt and enter sfc scannow Enter (there is a space between sfc and ), insert the original system disk to repair the system, and the system will automatically compare and repair.

It is recommended to call to confirm the specific time schedule of the maintenance center, and if you cannot get through on the weekend**, it is recommended to call from Monday to Friday.

We hope you find the above reply helpful.

Have you deleted the files under the C drive?,If you can't start it, you can only change the system.

Press F8 to select safe mode to enter or enter the last correct way.
