First solve your virtual memory problem. Do you play many big games? Like a big stand-alone game? If you don't play big games, you can completely turn off the virtual memory;

Secondly, if you don't want to close the virtual memory, you can transfer it to another disk, such as disk D, which is mine. Specifically, there is a program in the right-click computer-properties-advanced system settings-performance-settings-advanced, which is changed by a single computer. After entering, cancel the top check, then select disk C, and the paging file can be closed by single machine. Select the D disk above and customize the size. Both of them can be changed to 4039. Finally, change the settings and click OK.

I will teach you how to clean drive C: First, delete the hibernation file. After starting to search for cmd, right click to run as administrator. Paste the powercfg -h off command after the cursor. Look at your C drive again. How many G spaces are there?

Also, you have installed a lot of software, all of which are backed up on disk C, some are hard disk backups, and some are software backups. Actually, it can be deleted completely. It is best to optimize the main control with win7. There is a system disk to lose weight. Then analyze it. Finally, just keep the wallpaper and delete everything else.

I hope my answer can help you.
