If you were able to click on a Disable, did it do anything?

If you mean the Teredo Tunneling, then yes. I disabled and it now has a black arrow pointing downwards, with a white circle around it.

But I haven't done these two steps yet ;
7. Right click on “6to4 Adapter” and select “Disable”.
8. Right click on the selected network card (Wireless or LAN) that you are working
on and click disable, then re-enable it. This is simply to refresh the card which
can also be done via reboot.

As I don't see the 6to4 Adapter. Should I skip to step 8?

I guess if 6to4 isn't there, you can't do anything to it. Do what you can with the above and see if it helps.

https://www.youtube.com/watch?v=m8UdZ0PZm6Q I did as shown on that video to fix the issue with the Teredo Tunneling and it now has no exclamation mark, neither does any of the stuff shown in device manager. They all seem to work now.

But the issue is still here, and now it seems to flicker even at start up( i rebooted). It did not flicker at start up before.

So far i've tried to change to the screen resolution, and screen hertz is on 60 as there are no other options. I changed the text size to 125%(medium), still it did flicker.

I can't see any marks on the screen itself nor have I dropped the laptop in any recent time, if this information is of any help. Starting to get a bit frustrated.

Other suggestions?

I actually visited that site today via searching on google before I made this thread, and followed the steps. It still did not help.

The only thing I didn't do was the last two steps (check the video card, and the check the monitor) because I don't feel comfortable enough in my IT knowledge.

Is your monitor a flat screen, maybe an inch (2.5 cm) thick?

I don't know what that means, sorry. It's a laptop, with the usual 15.4".

Above you say "screen resolution" but then you say "125%". Did you actually go into your Control Panel and change the resolution? Mine is 1440 X 900. I just want to be sure everything is covered.
