None of the above worked for me. I had already tried the Windows Troubleshooters, but I tried again just in case. I had also checked the file sizes and types for each site from earlier, but all were within parameters. There was a driver update, but that did not change the result. And I performed the Clean Boot State, and checked on my regular and new user account in the clean boot state and back. Both were failures.
I have to say I am quite stumped.
I'm having similar issues. I've tried all of those methods too a few times. My issue is only certain websites that won't display images and I also have a karaoke app that I use offline that won't play the words but the music plays fine. I've used the same file from a memory stick with the same app on another computer and it works fine. There's gotta be some setting(s) not right on my laptop
