I've got a 3-year old HP Compaq DC7100CMT with 4GB RAM and installed a fresh, clean install of Vista SP1 OEM copy on an NTFS-formatted HDD. What's strange is that Vista SP1 won't successfully reboot the computer when I tell it to. If I wanted to shut it down, it will do so without incident. However, if I choose to restart, it will leave Windows and go all the way down, but then it will just hang there; right when the hand-off from POST to Windows takes place.
I know that this wasn't an issue with Vista pre-SP1, because all was fine up until that SP1 "upgrade" was added. The OEM SP1 media I'm using is HP factory pressed, so it's not a case of a poorly slip-streamed newsgroup version of SP1 that's causing the reboot failure. I've performed every repair option known to Vista, but none of them made any difference, whatsoever.
I've flashed the system BIOS twice with the hope it would right itself, but that didn't help. I even reverted back to my system's default BIOS settings and tweaked the boot options list so to not give the PC any other drive to boot from, other than Primary HDD 0; thinking that perhaps there was an issue with the PC deciding which of the on-board boot devices to boot from, but that didn't help, either.
If anyone has any suggestions/resolutions for this, please let me know.
Thanks very much!
