Infamous BSOD: Can only boot into VGA mode

B

brian.binkley

Good evening,

Well, I hope your's is better than mine. The short version of my story
is my WinXP computer now only boots into VGA mode. Here's the long
version of the story:

Yesterday morning I was using the computer and all was well. I left it
on all day and in the afternoon when I went to use it, the keyboard
wouldn't work. The mouse was okay so I did a shut down and connected
the keyboard to another computer, and that turned out okay. So I
rebooted my WinXP and right after displaying the WinXP black display, I
got the infamous Blue Screen of Death. So I shut down and did another
reboot into Safe Mode. Once again, I got the same BSOD during the
WinXP boot process. It never gets to the log-in screen. So I tried
rebooting again, this time using the "Last known good configuration."
Same results. I tried these three options over and over again, to no
avail.

The error message I got was:

Stop: 0xc0000005, 0xBF841D63, 0xBzzC1AEC, 0x00000000
Win32k.sys - Address BF841D63 base at BF800000, Datestamp 43446a58

I then went into the advance boot options and I was finally able to get
a log-in screen by going into the VGA mode. When I clicked on my
typical user name (setup with admin privledges), I got the BSOD again.
So I rebooted again and this time used a user name I setup for my wife
(also with admin privledges) and amazingly it got me to the desktop.
As soon as Norton started up though, it blue-screened on me again.

So, I tried again with the VGA mode, but for the next 12 times, it kept
blue screening me. On the 13th try, I was able to get back into my
wife's profile and killed the Norton app before it blue screened.
After seeing that the contents of my hard-drive still existed (phew,
didn't lose my data) I did a manual virus-scan and came up empty.

I'm at a loss of what to do. I even created a new profie with admin
privledges, but that too blue screens when I try to log into that. The
only profile that works is my wife's (and she never even uses the
computer!).

Any thoughts, ideas, or suggestions?

Thank you very much in advance,
- Brian

First of all back up your data. If you cannot do this from your current
install get a copy of the Ultimate Boot CD for Windows (
http://www.ubcd4win.com/ ) this includes cd burning software or
(provided you have a thumb drive or external USB drive that is pluged
in before booting the CD) you could save the data to a USB device.

Next try a repair install :-

Hi Brian,

0xC5 is usually caused by drivers, from VGA mode uninstall your display
drivers, then reboot normally. If successful, download the most recent
driver build from the video card manufacturer and install them.

The weird part about this, which I didn't mention, is that I haven't
installed any new hardware since Thanksgiving (the video card is
original, about 3 yrs old) and I haven't installed any software in
about a month. I thought about trying to switch out the video card
tomorrow and see if that makes a difference. But it doesn't make sense
why it'll only boot into one profile and not another. At least it
doesn't make sense to me.

I appreciate your input thus far.

I'll be sure to post a follow-up when I've concluded to the problem, or
conceded, whichever comes first. :)

Hi,

Files can become corrupted, and that may be what happened here. Removing
them may allow you to return to normal mode.

Oh yeah, one more thing. Did I mention that once I'm able to log into
VGA mode that I can't shut the computer down any more? I've tried
numerous ways of shutting down, even by typing in the command at the
command line prompt. The only way to shut down is by hitting the power
button the case.

Frustration ...

You might want to boot to whatever non-standard method gets you a
workable desktop. First thing I'd do is go to Add/Remove in Control
Panel and uninstall your Video card driver package. Because you've
abruptly powered off, your system partition likely has inconsistencies
on it - so you need to do a Chkdsk C: /F (Your data is backed up ?).
You may also have "Phantom" entries in the Display Adapter category.
I'd add the environment variables:
DevMgr_Show_NonPresent_Devices
DevMgr_Show_Details
and set both to a value of 1. Then Open Device Manager, click View,
tic/check "Show Hidden Devices" and expand the Display adapters
category. Any entries shown in diminished tone (Grayed out), Right
Click each one and take "Uninstall". Repeat this process for Monitors.
Reboot - XP should re-enumerate the Video but unless it has native
drivers it may detect as the default "Standard VGA". Then you can
get online and download the latest driver package for your card or
Motherboard Chipset video.
