Why is the computer card?

　　1.CPU temperature is too high

High CPU temperature caused by the problem of computer cotton is generally more common in laptops, because the thermal performance of the notebook computer is relatively poor, and often run large software and games, it is very prone to overheating problems. Especially in the environment of high temperature, the heat dissipation zone is blocked by obstacles, will occur due to the temperature of the cotton phenomenon caused by too high. For this reason the cotton, we should first clear the heat dissipation area barrier, for example, do not use the keyboard membrane, remove the object blocking the vent, stop operating the computer or shut down the computer, and so it will be used after the temperature drop.

　　2. Virus program

Some virus program intrusion will also cause the computer's cotton phenomenon, it will occupy a lot of computer resources, especially CPU and memory resources, so that the computer cotton, operation is very inconvenient. For the virus-induced cotton, our primary task is naturally to clear the virus inside the computer. Use anti-virus software to scan the computer, then clear the suspicious program, after the successful removal of the computer to restart it.

　　3. System garbage Too much

It is well known that computers can produce a large amount of cached junk files when accessing the network and watching video, as well as the residual garbage files when uninstalling the program. These garbage files will take up a lot of storage space, resulting in resource allocation of the system will occur when resources are not used, so that the efficiency of computer processing programs greatly reduced, producing cotton phenomenon. Therefore, it is very important to use anti-virus software or security management software to scan the computer's disks regularly, and to clean up the garbage files .

4. Too many programs running at the same time or too many system disk setup programs

When a computer runs many programs at the same time, CPU and memory are very prone to resource provisioning confusion, the computer is in a state of stagnation, producing cotton phenomenon. In addition, the excessive installation of programs in the computer on the system disk can also cause a higher probability of cotton phenomenon. Therefore, we should always pay attention to the use of the computer in the process, do not force too many programs, but also to be careful not to install all the programs in the system disk, in general, in addition to anti-virus software and security software can coexist with the system disk, the rest of the program and software should be installed in another disk, Save space for system operation.
