Toshiba Sli3 Hangs on reboot???

I have had my Sli3 about 3 weeeks now. I have a problem that when I do a cold restart or hot restart; it may hang on the "Windows" name on restarting. If I do a hard reset and reboot; it asks me if I want Windows to repair itself and I say NO; except one time I said yes. I only called tech support one time, not about this problem; but when I was getting Nvidia Driver stop and restart messages during a movie or a game. They told me to re-install the Video drivers; and On my next call they would have me do a re-image if that didn't work. Instead I learned about this forum and Laptop Video2GO; and have been using newer modified Nvidia drivers: 169.04; 169.17. Since using these Drivers I have never had a Driver stop /followed by recovery problem.

My problems with the restart hang, are less but not gone away. A few other things I have done to my system; is install 4GB Ram. I have found 3 main Vista Updates which may have related to the problem. A Vista Patch for 4GB Ram installed; and a Vista Hotfix for dual GPUs. I have not wanted to re-image my system because these problems seem likely Vista Issues and /or Driver issues and I could re-image all day; and they wouldn't go away. Anyone else with experience or thoughts; the system is great otherwise.
