Hey guys, I'm not sure where this topic should fall, but here it is:
When playing KOTOR (1 and 2), WoW, BF2, or CS:S, the menus and gameplay with run smooth for a few seconds, then stop for a few seconds, then continue and repeat this cycle infinitely. I have the latest patches and drivers, and have tried several re-installs. I did switch to a new CPU (X2 4200+, from a 64-bit 3500+) around the same time that this issue came up, but it did work for a bit, i believe. BTW, Medieval 2 Total War works like a charm, so it isn't all games. And all the games I'm playing right now are legit games bought by me.
I have also done a few spyware sweeps and my system is clean.
My specs are as follows:
AMD X2 4200+ (s939)
ASUS A8R-MVP Deluxe
XFX 7900 GS 256MB
2GB OCZ Plat. DDR400
200GB Seagate SATA
Sometimes weird things come up and I usually just reformat or lately I use Acronis true image to go back to a clean install that I know worked before. I would recommend the full reformat if it really bothers you.
