More than likely it is a driver problem. You have turned off everything
that would prevent a Normal bootup.
The only thing left would be someone mucking around with the:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows
NT\CurrentVersion\Winlogon\Notify
key entries. Sometimes, if you don't have a very good Firewall, someone
installs an entry in there. This entry is used when the system starts up.
You have two options:
1. Reboot and select Debugging mode and monitor the output and see where it
stops (driver name). Hopefully you have Auto restart off on failure. The
menu has this option Disable restart (or something like that).
2. Turn debugging mode on:
Add the following key value under:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
UserEnvDebugLevel DWORD 0x30002
Reboot under Normal. Make sure you have turned off Auto reboot on Failure
under Control Panel | System | Advanced | Startup and Recovery. This will
prevent Windows from crash and automatically reboot and keep doing it.
When you reboot after the Registry change to Winlogon, a file will be
created (aborted since the system will not come up all the way) under
C:\Windows\Debug\UserMode - named userenv.log.
After you fail, reboot (REMEMBER to turn that registry value off - just
rename that key in case you need to ever do this again AND Add to
Favorites - so you can always find it). Reboot in Safe Mode. Look at the
file contents. Remember, you will have two different sections in there:
1. Session of failure
2. Session after reboot into Safe Mode prior to unsetting registry key.
Hopefully, you will see where you were when the crash happened on the first
section.
Once you get Windows XP up and running ... do you have the Windows XP CD?
If so, you should run:
winnt32 /cmdcons
from the i386 folder (unless you have the i386 folder already on your hard
drive). This installs the Recovery Console onto your hard drive and adds an
option to the bootup menu to reboot in Recovery Console. You then don't
need to use the Window XP CD Recovery Console from there again.
Regardless, there is an option under Recovery Console called: listsvc(s).
This tracks down all the drivers and services. You can also ... once you
know the offending driver or service ... disable it from there.

Hi,
I have disabled everything to do with Norton/Symantec but fails to load. I
have also ran chkdsk with no reported problems.
Could this be a driver problem?
Thanks

If you rebooted in Normal mode and nothing, try (after I read some of
your
other posts) booting in Safe Mode, run SERVICES.MSC and mark anything
Norton
as Startup Type Disabled.
Then Reboot in Normal.
By the way, have you run chkdsk /f /r c: to insure the hard drive is
good?

Hi,
Made the changes to the registry (only three items listed - ) and
checked
the start-up folders, but all empty.
I have tried booting in last good configuration but no joy.
For some reason I do not have a restore point however this option is
running.
:
The reason, in MOST cases, why Safe Mode works is because it prevents
any
Startup Programs and support Drivers from Starting.
I would first, after booting in Safe Mode, open the reigistry and
rename
the
Run keys under
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
Then reboot in normal mode. I would also check:
C:\Documents and Settings\All Users\Start Menu\Programs\Startup
C:\Documents and Settings\[USERNAME]\Start Menu\Programs\Startup
and move anything there out to someplace else.
If the system reboots after these steps, then something is in the Run
keys
or Startup folders that is causing the problem.
Have you tried booting in Last Known Good Configuration? What no
System
Restore points? Did you turn the System Restore feature off?
Ok, this is my problem. Windows XP (Media Centre version) hangs
during
startup. Displays the logo and scrolling blue bars but that is it. I
am
able
to start in safe mode with no problems (in safe mode, with network
and
command prompt).
This is what I have done so for:
Scan Disk - no reported problems
Defrag - no problems
Clean boot - msconfig, un-ticked all in selective start-up, but
fails
to
load in normal mode (tried with and without "windows essentials"
running
in
the services tab).
Diagnostic start-up, again fails during normal start-up.
Anything else I can try??
Would repair windows installation work?
Many thanks
