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 start-run-input.
"%temp% "—-OK.
3. Clean registry and junk files with optimizer or super rabbit.
4. Close some startup programs,
Start running MSCONFIG. Start.
In addition to antivirus software and input method, general programs can be closed.
5. Delete the unused program software.
6, defragment the disk-start
-All Programs-Accessories-System Tools-Disk Defragmenter-Selected Disks-Analysis-Defragmentation.
7. Reduce the memory burden
Don't open too many programs. 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.
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 setting method of virtual memory is:
Right-click on 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 Settings, and finally click OK to exit.
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 optimization master or super rabbit to optimize the computer.
These methods have been used, the computer is still a card, you have to check whether there is something wrong with your hardware, or try to change the system.
