1. It is estimated that too many historical files accumulate and take up too much memory! 2. The configuration of the computer itself is low. 3. The weather temperature is high and the CPU cools slowly. 4. Computer poisoning or malware. 5. There are too many open processes. Here's how. 6. Graphics card problem.

There are too many methods here ~ 1. The simplest thing is to turn off the number of processes! Open the Task Manager! End several useless processes! But if you don't understand, don't just turn it off. If you turn it off wrong, you have to start over. I have a deep understanding! Mine is all closed to 18! Needless to say, Super 2. Just add memory1g. Generally, it will be quick if you don't play any big games! Because the computer space is large and the work is convenient. Essentially the same as the above method ~! 3. Adjust the refresh frequency! Right-click the desktop-Properties-Settings-Advanced-Monitor to adjust the refresh frequency! But let's talk about the general refresh frequency of LCD machine first. The default value is 60 and the maximum value is 75, which is a safe range. However, the greater the frequency, the shorter the service life! The desktop is much bigger, and all the good ones can be picked up at 120! It's best not to turn it so high ~ 4. If you can find the running program in the process, you can right-click it and set it as the priority! 5. It is suggested that the next six optimization masters, such as safe360, regularly detect system vulnerabilities and malware, optimize and delete some historical files!
