My problem is when I start CS5 Premiere Pro the preview windows for source and Program are blank, I can' see any of my selected video. I have tried with .mts, .mov and .avi files within CS5 Premiere during editing and no luck. I have imported my video and added it Sequence timeline below,.. I just can't preview the video.

However after I reinstall the NVIDIA driver 260.99 (latest release) for my Asus NVIDIA GTX 470 card, everything is fine in CS5 and I can continue on with my editing. That is until the next time when I restart my PC and discover that the my video previews are blank again.

So whenever I start up my PC to do some editing it seems I need to reinstall my drivers just so Premiere Pro can work fine. BTW, during the NVIDIA install process I do select
Custom>> then CLEAN INSTALL>> of the NVIDA drivers

Please what am I doing wrong in my NVIDIA driver installation or CS5 software or hardware setup?
