Hi,

Yesterday I got a new Pc and its working just fine most of the time but Ive been having trouble with some newer games like UT3 and Bioshock. Every 30 seconds I get a heavy lagspike for a few seconds and I just cant figure out why its doing that. Wheter I play it at minimum or maximum details , high or low resolution , antialiasing on or off , even if Im not playing at all and just standing still on a tiny map with nothing happening at all it keeps laging . Im not playing them online , so its not my connection either .

My Specs are :
XFX Geforce 8800 GTX
Intel Core2Quad Q9300 2,5 ghz
4gb Ram
Running on Windows Xp installed yesterday

It should have enough power to run these games.
It would be nice if anyone could help me trying to figure this out.
Thanks.
