Why does my computer suddenly fail?

Are you an integrated graphics card? If it's you, see if your graphics card is broken.

It could be a problem with the monitor! The icon becomes larger because there is a problem with the setting yourself.

What's your monitor?

or Old?

The graphics card driver is missing, so reinstall it.

Are you LCD or flat? In this case, like you said, like the graphics card driver is dropping, see if you have any software that conflicts with the graphics card driver. Or just update the graphics card driver, and if you're sure it's not a driver problem, take a look at your monitor to see if it's a bit of a quality problem.

Run to open the registry, find the hkey current user control panel desktop windowmetrics, find the string value in the window on the right: "shell icon size", change its value to change the size of the icon. Usually the number is "32".

Note: Before modifying the registry, please back up the registry beforehand.

This is a software issue. It's usually a big game launch that comes back and forth.

Right-click on the desktop -- >> Properties -- >> Settings -- >> Adjust the resolution a little higher.

If it still doesn't work, you need to reinstall the system.

1.First of all, rule out the cause of the virus, use antivirus software, such as the latest version of 360 Antivirus Quick Kill 3 5 minutes, according to the inspection results, click to deal with it immediately.

2.If the application error prompts that a file is missing, it may be that the file is corrupted, according to this component to query which system component is damaged, reinstall the relevant component, restore the program file, and generally solve the problem.

3.If the components of the software itself are missing, you only need to reinstall the software. For example, when running Thunderbolt, it prompts that a certain file is missing, you can try to reinstall Thunderbolt.

4.If the above method does not work, it may be a conflict between the software. The workaround is to try closing a couple of unrelated running applications and see if the error will reproduce.

If it has been resolved, you will know which two software conflicts are and can be resolved by not running both software at the same time. Or feedback the fault to the manufacturer and urge the manufacturer to upgrade and solve it. If you don't know which software conflicts, the feasible solution is to use 360 Security Guard's system optimization, and in one-click optimization, turn off some infrequently used software startups.

In this way, there are fewer programs running after booting, and the probability of collisions will decrease.

5.For another application error, the screenshot shows "the application is faulty, the **memory address cannot be read or written", this situation is the most complicated, if the above methods can not be solved, it is likely to be a hardware (mainly memory) failure, may be poor compatibility, can only contact the hardware ** vendor for repair. Or reinstall the system, which may be effective for a short time after reinstallation.

If the router is broken, or the outdoor bus is worn, or the operator is faulty, you can call the operator to which your broadband belongs** for troubleshooting.
