Computers often get stuck after installing win7 system. I don't know if it's a memory problem or a graphics card problem.

1, check the computer configuration. If the physical memory just meets the minimum configuration requirements of win, it is recommended to upgrade.

2, the graphics card is best to choose a single display with more than 256MB of memory.

3. It is suggested to optimize the system.

1) startup items need to be set, and unnecessary startup items need to be closed to improve the system startup speed.

Method:

Start-Run-Enter MSConfig-OK.

Click-Start-Uncheck Antivirus and Input Method-OK-Restart the computer.

2) Use the disk tool that comes with the system for cleaning.

Method: Right-click drive C- Properties-click Disk Cleanup-Check the scan results-OK.

4. Optimize and clean the computer with the help of third-party software 360 security guards.

5. Use the 360 security guard plug-in function to move the C disk and slim down the system disk.
