I just installed my 2.6c CPU and the WinTV2000 tuner app starts freezing after a minute or so. It never did this before when I had my 2.53b installed. It freezes even at stock speed. 3D games work fine however. I even tried the lastest driver and WinTV2000 app revision. Do you think an XP re-install would fix this? I didn't re-install my OS after installing the CPU. If anyone has experienced this or something similar and have found a solution let me know. Your input would be greatly appreciated.
