It took me 5 months to figure it out. After I finally eliminated all possible hardware possibilities I installed an extra hard drive Installed Windows 7 64 bits and Fusion 3.81 the driver for my FusionHDTV 7 Dual Exptess HDTV TV Card. Windows corrupted in less than a day. By corrupted I mean it wouldn't restart or shut down amoung other problems. I uninstalled ZoneAlarm and the problems went away. I rebooted from the original hard drive that had Windows 7 64 bits and all my other programs. I uninstalled ZonwAlarm and all problems were gone!! The latest dowbload available is the same I had installed.
