So I just built a brand new computer. Asus A8S-X mobo AMD Athlon 64 FX 60 Dual Core Nvidia Geforce 7950 GT 1 GIG DDR400 It is fast as heck, but the video is not right. When I run HalfLife2 and no matter how low I make the settings, it gets very choppy; as is for every game I try to run. Also I'd like to note that when I am not playing games (surfing the internet, or messing around on photoshop) sometimes the mouse seems like it doesn't flow across the screen, and whenever I scroll down on a page(internet explorer etc.) it doesn't scroll down smoothly. I have the latest drivers for the video card too. Anyone know what the problem might be?
