Reset Virtual Memory in Windows 10

By default Virtual memory uses your HDD disk as RAM. When your computer runs out of memory, it will use your system drive to store files temporarily and will swap those files back when required.

C is the drive letter where the windows installed. The “/f” parameter tells CHKDSK to fix any errors it finds; “/r” tells it to locate the bad sectors on the drive and recover readable information Save your current work and restart windows to allow chdsk command to check and fix disk drive errors. Wait until 100% complete the scanning process after that restart windows and check if this fixes the problem or not. Also, Run the System file checker utility to scan and restore missing corrupted system files.
