1. Hardware:
1) Increase physical memory: If the motherboard has extra memory slots, you can add memory that matches the original memory model specifications. You can use tools such as Master Lu to detect the memory model, as shown in the figure below.
2. Software:
1) Increase the running memory. You can use 360 Security Guard or software with similar functions to regularly clean up and optimize the acceleration of the computer to remove unnecessary boot auto-start programs and various plug-ins.
2) Regularly check and kill Trojan viruses. It is recommended to regularly use 360 Security Guard (focusing on network security) and 360 Antivirus (focusing on local data security) or similar software to conduct a comprehensive search for Trojans and viruses, and do not load too many antivirus engines.
3. Operation habits: develop good computer operation habits, do not run multiple large software at the same time, close unnecessary programs and windows in time, and clean up memory in time.
