BSOD Problem

[Guest]

When booting up normally I consistently get a PAGE_FAULT_IN_NONPAGED_AREA
BSOD STOP ERROR (x00000050).

This occurs BEFORE the Welcome Screen, and before the keyboard lights (Num
Lock, etc.) flash On then Off.

This just started several weeks ago. I had not installed any new HW or SW.

If I first boot into Safe Mode (which boots OK), the click on Start -> Turn
Off Computer -> Restart, Windows will boot normally with no BSOD.

I set the BOOT.INI /NOGUIBOOT and /SOS options which displays the drivers
being loaded on the screen and I see no difference between a normal boot
(when I get the BSOD) and the boot into Safe Mode.

What is different about a normal boot (Power On switch), and a Restart from
Safe Mode?

Is there any way I can single step through the boot process and see what is
loading and figure out what might be going wrong?

I've run hardware diagnostics, Norton Antivirus, Ad-Aware, Spybot, CHKDSK
with no errors found.

Any suggestions would be appreciated. My computer manufacturer has been
unhelpful and their only suggestion is to reformat the disk and reinstall
everything which I don't want to do unless I can find the root cause of this
problem so I don't go through all that pain and find out the problem still
exists.

Thanks.

Hi,

There can be several causes of this error, usually driver related. Is there
a file mentioned in the stop error message screen?

No, there is no file or driver mentioned. Also there is no small memory dump.

Another interesting fact though. I enabled boot logging, and now the problem
seems to have dissapeared. I'm beginning to believe that there is some sort
of bus timing problem, and that enabling boot logging has changed the timing
of things somewhat and made this problem seem to (at least several times so
far) go away.
