No, I am still using the Voodoo3. All appears to be o.k. with the CPU and fan, and I check the heat sink on the V3 immediately after a lock up and it is quite cool with the fan I installed on it. It is very strange, as AH is the only application that this happens with. All other games work fine, and all other Windows apps do as well. The problem didn't occur with the Voodoo2, but only appeared after the V3 was installed. Between the V2 and V3 I had installed a Creative 3D Blaster TNT2, which worked great in AH, but made Windows totally freak some times, causing the current application to start jumping all over. I never was able to get it stable in Windows. I removed it and installed a Guillemot MaxiGamer Cougar TNT2, PCI version, and couldn't ever get it to act stable in anything... games or apps. I finally decided to return to the Voodoo line, as I have previously had a V1 and V2 with great results. The V3 works great for everything else (some glitches in the TV software though), but I can always count on a lock up after a few minutes in AH. Lock ups happen in both online and offline, and under different conditions. They don't seem to be related to any particular action or graphic display on the screen. They definiitely aren't happening due to smoke, as I haven't been able to fly long enough to get to any action before it locks up. I also got an old copy of version 0.38 and tried it to see if it was version dependent, and the same lockup happened. I downloaded the latest V3 driver files from 3DFX and still have the problem. I even tried installing DirectX 5 from an old install file I still had to see if the latest ver. of DX was causing it, and the only difference was a slower frame rate, but the lockup still happened. I'm really stumped at this point.
