Here are two sets of instructions for you to follow. I hope at least one of them will help.#1. Try with System Restore
In case you were able to view YouTube videos with no problems before installing Soundfrost Video Converter
or any other program, you can easily revert the changes by using System Restore. It will restore Windows and program settings to an earlier point in time, when all worked fine. Here is how to use it:
1. Click the Windows Start
button and type system restore
into search box
and press Enter
(or click Windows Start
button and point to All Programs > Accessories > System Tools > System Restore
2. You should see System Restore
window. You will be given a choice to select either Recommended restore
or Choose a different restore point
3. Since Recommended restore
is usually one day old, select Choose a different restore point
and press Next
4. You should see a list of restore points based on a date. You can also tick a box that says Show more restore points
5. Select a date when you know everything worked fine
6. To confirm, press Next
and then Finish
7. Your computer will restart and restore all system settings to the date you selected
Don't worry about your personal files because they won't be affected by this process.
If it didn't help, proceed to the next suggestion.#2. Update DirectX and video and audio codecs
You can update DirectX files as well as video and audio codecs on your computer which are needed to properly see all videos and hear the sound.
So, first click on THIS LINK
to download DirectX updater
When downloaded, run dxwebsetup.exe
and wait until it finishes installing all the updates.
Once done, click on THIS LINK
to download K-Lite Codec Pack
. Run its installer and use default options to install the program. When installed, restart your computer.
After that, start Internet Explorer and check if you can successfully view YouTube videos. In case it won't work, please check with Mozilla Firefox or Google Chrome - whichever is available.
Let me know the results.
