Hi, I would suggest changing the web browser like chrome, firefox etc and also check the performance in "safe mode with networking".
If the issue still persists and If this issue started occurring after doing some recent software changes on your computer, then I would suggest you to restore your system back to a date when it was working fine. System Restore will affect Windows system files, programs, and registry settings only.
Thanks & Regards
