When the computer starts the game, the screen flickers, and the card is returned, and the machine fr

There are several reasons why the screen flickers when playing games on <> computer: magnetic field interference, incorrect refresh rate settings, incorrect graphics card drivers, and poor graphics card contact.

Magnetic field interference: Put the computer in an environment without a strong magnetic field to see if there will be a flickering screen phenomenon to completely kill the virusSome computer viruses will disrupt the screen display, causing character inversion, screen shaking, and other problems.

Incorrect refresh rate setting: The refresh rate setting is too low, which can cause the screen to shake.

Incorrect Graphics Card Drivers: If you find that there is no refresh rate to choose from, it is due to incorrect or too old drivers for your graphics card. At this time, do not use the drivers from the disc that came with your computer.

Go to the latest version of the driver of the corresponding graphics card on the Internet, restart the computer after updating the driver, if the driver is installed appropriately, the display refresh rate option will appear, and then set the refresh rate to 75Hz or more.

Poor contact of the graphics card: If it is a discrete graphics card, disassemble the machine and take out the graphics card, clean the gold finger with an eraser, clean the slot, and then insert it again.

First: Press the numlock key of the numpad to see if the keyboard indicator reflects, if not, you can only hard reboot or shut down.

The following is based on reflection).

Second: press alt+f4

Third: press Ctrl+Alt+The fourth type of active process for ending unresponsive tasks from Task Manager: CTRL+ESC (generally useless.)

You can restart the computer to see, it is normal for the general computer to crash occasionally, but if it is a frequent crash, and it is a crash after the flickering screen, then you have to consider whether it is caused by hardware.

Check the graphics card part, there may be a broken cooling fan, or poor heat dissipation, causing a black screen due to the temperature exceeding after a period of work, and after a few minutes, the temperature drops, and the boot is normal again. However, after the temperature is super high, the screen may go black again.

That could be an issue with the memory, running out of memory. If the host will alarm when it crashes, then you can listen to the sound of his alarm, as if 1 long and 3 short is a memory problem.

It is estimated that it is the reason for your memory module, take it down and plug it back in, if it doesn't work, borrow a separate one.

Causes and solutions for computer flickering screen and then crash:

1. Test the external monitor to see if the external monitor has a similar situation, so as to determine whether this fault is caused by the host part or the screen head part.

2. The external display is normal, please re-plug and unplug the screen cable interfaces on both sides and fix and check whether the cable routing at the screen axis may be squeezed and interfered with by other components.

3. The above operation is invalid, replace the LCD screen test, if the fault disappears, it is the LCD screen failure, and the fault still exists basically because of the screen line problem.

4. If there is a similar fault in the external display, you need to consider updating the graphics card driver, flash plug-in or restoring the system.

5. Software problems cannot be troubleshooting, replace the CPU test, to determine whether the fault is caused by the CPU or the motherboard.

1. Unplug the graphics card, polish the gold finger of the graphics card with an eraser, clean the graphics card slot, and then insert it back. Then boot it up and try again.

2. If it doesn't work, try it with another graphics card to see if the graphics card is broken, you can borrow the graphics card of another computer for testing first.

3. If you rule out the problem of the graphics card, it is that the motherboard is broken, and there is only the problem of replacing the motherboard or sending it for repair without turning off the monitor, because it can cause a crash, so it is not the cause of the monitor, and the monitor will not cause a crash.

Dear Lenovo users, hello!

Whether to update the driver or patch recently, if you have to uninstall the program and function in the control panel--- the screen will flash in safe mode, you can boot the computer and press F1 to enter the BIOS to test, the BIOS is flashing screen, the hardware is very likely, so you can send it to the service station to check the service station address query, if it does not flash, you can back up the data and reinstall the system.

How to uninstall the power management driver: Control panel--- Programs & features--- ThinkPad Lenovo Power Management Driver

How to uninstall the graphics card driver: Right-click on the computer --- management--- device manager--- display adapter--- right-click to uninstall, and check Delete files.

After flashing, it will crash directly.?
