ok so my computer was pretty good for awhile but now it needed an upgrade. i noticed i needed more ram because i only had one gig of ram. so i buy two more gigs and i see absolutly no change. i cant run anything better. especially games. i cant even use the defult settings for graphics on command and conquer 3. i have no idea whats up. i have a viiv processor, 3 gigs of ram, and a NVIDIA GeForce 7300 LE video card. i have no clue what to do. maybe the video card?
