Driver

Hello! First of i appoligize if this is in the wrong category in new here!

So i have a HP Pavilion dv6-6b90eo.
my problem is that after I updated some drivers: Chipset, Audio and Operating system (my computer told me i had to update these because they were old)
I recorde gaming videos i put on youtube and i Use Video Editors, my Problem now after the update is that In the Video Editors i use (Windows Live Movie Maker and Sony Vegas Pro 12) The recorded gameplay is a black screen with only gamesound. but if i watch the recorded Video Directly I can see the video and hear my voice and gamesound.
so what can i do to fix this?
iv been thinking of do a complete system reset on my computer because every time i had to update something something has gone wrong.
If i would do a complete Rebot of the computer whould all the problems go away?
what can i do to fix the no video and "my voice" problem in the video editors?
and if you know the drivers i should use can you please send a link to those exakt Drivers?
Thanks!
