2. Check for updates: Make sure that your operating system and drivers are up to date. Open Windows Update and check for any available updates. Also, make sure that your antivirus software is up to date.
3. Check for disk errors: Use the built-in Windows Disk Check utility to check for any errors on your hard drive. Open File Explorer, right-click on your C: drive, select "Properties", go to the "Tools" tab, and click on "Check" under "Error checking".
