I rebuilt a Toshiba Tecra laptop (booted to XP CD, deleted the C: and D: partitions and created one large C: partition, did a quick format, and loaded Windows XP). After doing this everything appeared to load OK and I was able to boot on into windows and start with the driver installs (did not actually load any drivers yet though). Now when I reboot the laptop it will shut down and just go to a black/blank screen. I have to hold the power button in until it completely shuts down and then boot it up again. I am able to shut down with no problems. I have a Compaq 8510p laptop that is doing the same thing. I used the same CD and followed the same steps. Neither PC was doing this before the rebuild. I have flashed the BIOS on both the laptops with no success. I'm at a loss. Any help would sure be appreciated.
