FAQ'S regarding up grading my computer to 4gb ram and 9600 nvidia ?

No... your mobo does not support 4gb of ram. since you only have 3 slot of Memory and its an older type DDR1, max will be 3gb (3x1gb stick) and as for the video card. I dont think Nvidia make a 9600 on AGP platform the last AGP Nvidia made was back in the 7 serie card But I might be wrong.. AGP are getting replace by PCI-express. Better to built a new computer.
