So up until I got gta 4 my computer worked fine, sometimes I had lag, sometimes not, normal stuff.
But then I got Gta 4 and had to update my video card driver. I have a nivida geforce 7900, and directX 9.
It doesn't freeze on games like terraria, minecraft, maplestory, ect. But it freezes on Half life 2 and team fortress 2. So it's probably a video card thing.
Specs are:
System:
Microsoft windows Xp
Media center edition
Version 2002
Service pack 3
Computer:
Intel (R)
Pentium(R) D CPU 3.00GHz
2.99Ghz, 2.00 GB of ram
Physical address Extension
As I said before the video card is a nividia Geforce 7900 GS with directX 9.
