I've just reformatted my PC the other day, and ahve jsut finished getting all my source games back up. I've been having a few problems with EP2, Gmod and probably Portal/TF2 as well.
I'm getting really bad stuttering in the game menus and in-game. I mean like, I see movement for a second then it stops for 10 seconds and so on. I've looked around the steam forums, no answer. I've reinstalled Gmod (Because that's the game I need to work) nothing helped. I did notice something going on my my Task Manager that looks a bit odd.

The svchost, compared to what it was before I reformatted and now I used to have 1 in the Task manager (To my knowledge) and now i have 5 or 6, that they are munching my CPU up. I'm thinking this may be the issue but I'm not sure.
If anyone has any Ideas on what I could try to fix this please, your help is needed.
Thanks.
EDIT: And my Video Drivers are on the latest version too.
