Vista Tutorial - Freezes on Restart

Hello,

Problem 1:
I've installed the Windows Vista Beta 2 32-bit version and everytime Windows
restarts
my computer (due to initial installation or new software installation), it
freezes at the screen that allows you to access the BIOS and other options
(before Windows begins loading). If I restart the computer manually (using
the button on the front of the computer) or shut down using Windows,
everything works fine. It is only when Windows attempts to restart my
computer. This isn't a problem for software that allows me to restart
manually, but sometimes Windows forces a restart.

My Device Manager says that all of my hardware is up to date and it all
works fine; however, I didn't install any drivers. Additionally, Windows
Update has provided me the most recent critical updates.

Problem 2:
At first, I attempted to install the 64-bit version and sometimes during
boot up or when I would boot off of the Beta 2 DVD to install Windows, a blue
screen would come up and force me to restart. Unfortunately, I did not write
down the error code. But one thing it said was, "Disable BIOS memory options
such as caching/shadowing". In the BIOS, I disabled "External Cache" and
"C000, 32K Shadow".

But, now that I'm using the 32 bit version, should I enable these options?
The blue screen doesn't comes up anymore, but it may be because those are
disabled.

I believe my BIOS is up to date, but I do not know how to check. My
motherboard is the MSI K8T Neo-FSR MB and the BIOS is version 3.31a. I'm
running an AMD Athlon 64 2800+ 1.8GHz with an ATI Radeon 9600 XT. I have no
sound card (using motherboard) and my speakers are in my monitor. My hard
drive is NTFS and 60 GB.

Please help. Thank you.
