Ok, here's the problem. I uninstalled the drivers for my GForce 5200fx as well as the card. I installed the 9600xt, everything went fine. Thing is that whenever I play FFXI it starts off fine, but after a few minutes I hear a high pitched sound coming from my pc. Last time this happened the game locked up, completely froze. I keep adjusting my settings, but nothing seems to help. I dont feel its a heat issue as I'm running 5 case fans. Any suggestions would be helpful, I will list relevant stats below:
ATI Radeon 9600xt
Pentium 4 1.8 Ghz
Intel D845wn motherboard (agp4x capable)
512MB of pc133 memory
MS Windows XP Professional (all latest updates)
