this used to happen on my old machine, but it's happening on a brand new system with new hardware, except hard drive. It'll go through the motions of starting then the 4 colored balls will come up and then freeze, takes a couple reboots to get windows to fully start up. I've updated the drivers for my video card to win7 drivers (Nvidia 9400 GT) and freezes and restarts persist. Any help you can give would be invaluable. If you need any info please ask, with steps to get info please.. Thanks.
