Not sure where to post this but here goes..

I've looked all over google for an answer to this problem but was unsuccessful.

I bought a new m9700 with vista ( wasting one of my 512mb 7900GO).

specs are 2.2ghz amd turion , dual 512mb nvidia 7900GO, 2gb ram, vista
(tell me if you need specifics);

Anyway the problem is that I installed CS 1.6. All went well and I installed but before I even join a server I see that every 5 seconds or so my fps drops from 100fps to 20fps and jumps back in 1 sec. Its constant and very annoying. I have vsync off

Any tips?

Just tested it out on WoW as well as 3dmark

Fps is constantly spiking and very annoying to play on

please help
