Hello
It seems like you’ve already tried a number of troubleshooting steps. Here are a few more suggestions that might help:
For Chrome and Edge:
Disable Automatic Tab Discarding: In Chrome, enter chrome://flags/#automatic-tab-discarding in the address bar. This will take you directly to the Automatic Tab Discarding flag. Click the dropdown box next to the highlighted entry, and then choose the “Disable” option. You’ll need to restart your browser, but after that the feature should be disabled.
Reset the Browsers: Open the browser and click the 3 dots at the upper right side of your screen. Go to Settings. Look for Reset Settings. Click Restore settings to their default values. This will reset your startup page, new tab page, search engine, and pinned tabs. It will also disable all extensions and clear temporary data like cookies. Your favorites, history and saved passwords will not be cleared.
For File System:
Run DISM / SFC: Open cmd.exe with Run as Administrator. Then run the following commands:
DISM.exe /Online /Cleanup-image /StartComponentCleanup
DISM.exe /Online /Cleanup-Image /Restorehealth
SFC /SCANNOW
Restart your system when all the above is complete and test.
Check Desktop Background Slideshow: If you have a desktop background slideshow running, try turning it off (Settings > Personalization > Background).
