The computer has a problem, and sometimes the mouse moves on its own, and it also has a card of 20

There are three possibilities.

1: You first straighten the mouse line to see if this will happen.

2: Your computer is remotely controlled, it is recommended that the landlord pay attention to the update time of the anti-soft, after the upgrade of the virus database is completed, you will unplug the network cable, antivirus, and please pay attention to whether these ports are closed 135 3389 99 7626 1433 8000 139 445 593 1025 1027 1434 8080 If you check the port, you can run cmd in the run, and then enter netstat -an in the command prompt that appears. The landlord himself looked for a method of closure on the Internet.

3: If your mouse is plug and play, then you don't need to update the driver, if your mouse is too high, you need a driver when running, then update the driver.

If none of the above is successful, then you can reinstall the system.

I also wish the landlord a happy use of the computer.

Is it in the game that the landlord agrees? Then after entering the game, don't touch the USP excuse of the mouse, otherwise it will be If it's not in the game, restart it more, and if it doesn't work, reinstall the system Thank you.

Buy a wireless mouse, super convenient.

Your question was very detailed. It's been a long time since I've seen such a detailed question. I'm so grateful. Haha 1Make sure there is nothing wrong with your mouse first. The method is very simple, just take it to another machine and try it.

2.Troubleshooting From soft to hard, first determine whether there is a virus at work.

3.Pay attention to how long your machine has been used and how it is running. You feel like the inside won't be very dusty.

If the operating environment is not good. That's what the upstairs says. Dust the hardware of the machine, especially the gold finger.

Because it is most susceptible to oxidation.

1. Antivirus.

2. Use 360 security guards to check and kill Trojans and malicious plug-ins.

3. Use 360 software butler to reduce unnecessary startup of the computer 4. Clean up system junk.

Pull out the memory and graphics card, use the eraser to clean the gold finger, and the failure can be canceled when pressed back, which may be caused by oxidation of the gold finger or poor contact.

The failure is obviously caused by the incompatibility of the internal card, my computer has encountered a similar situation before, just change the memory!

If the mouse moves one card at a time, it is a problem with the internal parts of the mouse, and the internal parts of the mouse need to be cleaned.

The method of getting stuck and freezing when using the computer is as follows:

1. The CPU is overloaded, or it is not working properly. Check CPU and graphics card cooling, dust removal, oiling, or replace fans.

Second, the power supply voltage is unstable and the power supply is insufficient. Replace high-quality, high-power power supplies.

3. Clean and defragment disks frequently.

1. In the "My Computer" window, right-click the drive letter you want to clean up - "Properties" - "Clean Disk" - check the files you want to delete - OK - Yes.

2. Clear the temporary file, start-run-enter "%temp%"-OK.

3. Clean up the registry and junk files with Optimizer or Super Bunny.

4. Close some startup programs, start-run-msconfig---start, in addition to anti-virus software, input methods can be turned off in general.

5. Delete unused program software.

7. Reduce the burden of memory, and do not open too many programs. If you have too many documents open or too many programs running at the same time, you will not have enough memory to run other programs, so you should close the programs and windows you don't use at any time.

4. Upgrade the graphics card and network card driver, and change to a higher-grade graphics card.

Fifth, increase the physical memory, now the memory is generally at least 2G.

6. Set up virtual memory reasonably.

1. To play games, the virtual memory can be set to be larger, and the maximum and minimum values are set to 2-3 times of the physical memory.

2. The method of setting the virtual memory is: right-click on my computer - Properties - Advanced - Performance Settings - Advanced - Virtual memory change - Select the partition where the virtual memory (page file) is stored in the drive list - Custom size - Set the value in the "Initial Size" and "Maximum", then click the "Settings" button, and finally click the "OK" button to exit.

3. The partition where the virtual memory (page file) is stored must have enough space, the hard disk resources are insufficient, resulting in insufficient virtual memory, in a computer, it is enough to set up virtual memory in a partition, and it is not necessary to set it in multiple partitions.

7. Optimize your computer with Optimizer, 360 or Super Bunny, etc.

Changing the operating system is a one-size-fits-all approach.

The computer is very stuck.

1. First of all, you must ensure that the C disk has enough space, if the C disk is insufficient, it is easy to cause the computer to freeze, so in the process of installing the application, you must pay special attention to installing the program in other disks other than the C disk.

2. Secondly, it is necessary to ensure that your computer card is not caused by memory, and the better way to view the system in operation can use the computer butler small rocket, if you still have a high memory usage in the case of few open programs, then this time is to consider adding a memory module.

3. You can also use some of the functions that come with the computer manager to clean up, and it can be said that this cleaning effect is still very good.

4. If you are cleaning up the disk, then its steps are to right-click the C disk properties disk cleanup, so that it can be completed.

5. Defragment the disk, this step can also compress the space of the hard disk, the step is to right-click the "Start Decluttering" in the Properties Tools of the C disk.

If you don't have enough memory, you will also get stuttered.

First, disable some unnecessary boot items: shut down and restart, press "F8 key", select "Safe Mode" to enter the system, click "Start" Run" (or use the key combination "Windows key + R key") to bring up the run bar;

Enter "msconfig" in the run bar (or OK) to bring up "System Configuration";

In the pop-up system configuration dialog box, find the "Services" tab and click it, first check the "Hide all Microsoft services" item under the service label, then check all the non-Microsoft services listed in the above box, find out the services that need to be started at boot, and click "Apply" in front of the service item.

Click on the "Startup" tab, find out the unnecessary boot startup program, go to the previous "tick" and click "Apply" OK to "exit the "System Configuration", and restart the computer.

Start the computer normally and enter the system, and repeat the above steps again;

With the help of third-party tools, such as System Optimizer in PC Manager, the system boot is optimized again.
