After reboot Programs List states I have 18.2.1 but Radeon settings states that it recommends 18.2.1.

But then I get (AMD2 image) and then continue with the install of 18.2.1. Then I decide to install win7-64bit-radeon-software-adrenalin-edition-18.2.1-feb7.exe and do a clean install with 18.2.1 which reboots succesfully. I decided to install -whql-win7-64bit-radeon-software-crimson-relive-17.2.1-feb28.exe and at reboot I saw that radeon settings were active. So then I deleted that yellow registry entry because the file was missing. Then afterwards I ran the AMD uninstall utility I got this (AMD1 image). After the SR and using DDU I used autoruns by sysinternals to see what was autorunning in the registry (AMD image). I tried doing the install as you said with ccleaner but it didn't make a difference so I did a system restore to before CCleaner was installed. I also notice that I have installed latest software and drivers 18.2.2 according to windows programs list but Radeon settings is recommending to install 18.2.1? I am wondering if this something to do with Adobe Flash or DirectX. I have a short screen capture video (mkv) of what I see but I am not sure if posting it would be any kind of violation. But streaming archived videos online and some video files I have like mp4s etc the problem shows up. I have a subscription to sling and when viewing live tv I don't seem to have a problem. I have a Dell M770 monitor and the I also connect my PC to LG42TV.

I see this in all browsers: chrome, firefox, opera. I have been experiencing vertical lines showing up on youtube videos and other streaming sites. I am not sure if this is related to the video card, software or something else.
