Brand new F3Sv from a few days ago out of newegg. First thing I did was stick an extra gig of ram into it.  Everythings been going great so far except for one big gaming problem.  After playing maybe 10 mins of gaming some weird things start happening.  The game will sort of alt-tab real fast exposing the title-bar hilight text in the upper left corner and relocating the cursor up there.  Games then start running very choppy, when moving around or doing anything really the  problem worsens.  When I alt-tab out of the game, for a quick second before it switches I can see a black-ish text input thing in the upper-left corner of the screen, the text input field is filled with random chinese (I think) characters and stuff.  Lots of beeping (vista error noise) when doing things in game when this is happening.  I tried to take a screenshot of the text input thing but I couldn't catch it in time. I went through all the services and processes running and everything looks legit.
 
Here's my hijackthis :
 

 
I've messed with the video setting and stuff to try to fix it but to no avail, reinstalled all the ATK stuff because I assumed that was the problem, no luck either.
 
Pretty weird problem if I must say, any ideas?

Got a better look at the problem.  It seems to be that the text input is freezing my game when i'm using keys.  The keys I guess are inputting text into the field and is the reason the game loses focus.  The input is a black rectangular box with a white text input area. Text is dark bold black. There's a green return like symbol to the right of the input field, must mean submit.
