Windows 7 bug help.. (64 bit)

I currently just set up a new computer running windows 7 64 bit and whenever I am running a game the computer will freeze for 1-2 seconds then resume play. This is particularly annoying when I am playing action games such as counter-strike.

Windows 7 Professional (64 bit)

AMD Phenom II X4 955 Processor

ATI Radeon HD 4870

Gigabyte ga-770-ta-ud3

4gb ddr3 1333mhz

I was thinking about swapping out the ram for another brand, but idk what else to do

Doesnt happen to me on Windows7 64 bit

Are you sure another program isn't just hogging the ram? or tried updating drivers?

Is the hard drive usage light flashing when this happens?

i never notice a hard drive light on at all. and this is my first brand new install so drivers should be good. ram is never being fully used so its not getting hogged

im thinking maybe its my wireless card? because i have never had lag issues but for this comp i got a new linksys wireless card and i tried playing a singleplayer game and it never did the 1 second freeze

Try an ethernet cable?

I used to get this on occasion and it was always due to one of two things. It was either the graphics card driver or it was my SSD causing it to stutter (was an older one which didn't have TRIM support). Since updating drivers and replacing the SSD it's gone... for now.
