First, the CPU load is too large, or it is not working properly. Check the cooling, dust removal and oiling of CPU and graphics card, or replace the fan.

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

Third, always clean up the disk and defragment it.

1. In the My Computer window, right-click the drive letter to be cleaned-Properties-Clean Disk-Check the files to be deleted-OK-Yes.

2. Clear the temporary files, and then start-run-enter "%temp%"-OK.

3. Clean registry and junk files with optimizer or super rabbit.

4. Close some startup programs and start-run -msconfig- start. In addition to antivirus software and input method, general programs can be closed.

5. Delete the unused program software.

6. Defragmentation-Start-All Programs-Accessories-System Tools-Defragmenter-Selected Disks-Analysis-Defragmenter.

7, reduce the memory burden, open the program should not be too much. If you open too many documents or run too many programs at the same time, you won't have enough memory to run other programs. Close unused programs and windows at any time.

Fourth, upgrade the graphics card and network card driver, and change to a higher-end graphics card.

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

Sixth, set up virtual memory reasonably.

1, to play games, the virtual memory can be set larger, and the maximum and minimum values can be set to 2-3 times of the physical memory. If it is large, it will take up too much hard disk space.

2. The method of setting virtual memory is: right-click my computer-Properties-Advanced-Performance Settings-Advanced-Virtual memory change-select the partition for storing virtual memory (page file) in the drive list-customize the size-set the values in the initial size and maximum value, then click the "Settings" button, and finally click "Settings".

3, virtual memory (page file) storage partition, must have enough space, hard disk resources are insufficient, resulting in insufficient virtual memory, in a computer, it is enough to set up virtual memory in one partition, not in multiple partitions.

Seven, use the optimization master, 360 or super rabbit to optimize the computer.

Changing the operating system is a panacea.

I hope I can help you and adopt what is useful to you. ..
