Hello, I am stuck. I just bought a used xp3800 dual core, an Asus A8N32 - sli mobo, an EVGA 7800 gt sli videocard. 2 gigs of ddr 400 running in dual core. I have 2 western digital 120 gig sata hard drives running in a raid 0 setup. Heres my problem I just did a fresh format and install winxp pro 32 bit edition. I didnt have a cd with the mobo so I went to Nvidia and downloaded the chipset and videocard drivers. I also downloaded and installed the AMD cpu driver. I then went to Asus and installed all the devices. Whenever I try to run Battlefield 2 the system runs really slow, the game is so choppy its unplayable. Did I forget to install a driver or something ? I have avg free antivirus running, I did a check with trendmicro free online scan and didnt find any viruses. My g15 keyboard shows my cpu is 50% and the ram is 23 %. What did I forget ? or do I need a 64 bit windows ? thanks
