Helping a friend and I'm stumped
A W2K Pro computer fails with a STOP 0x00000050 PAGE_FAULT_IN_NONPAGED_AREA blue screen and then reboots. Installed programs include Norton Antivirus and Nero Express OEM (recently installed!) I mention these as I think they may have a bearing on this problem.
Recently my friend got some sort of virus and removed it per instructions from Symantec - I don't know if any error on his part there might be relevant to this issue.
After the computer has essentially booted it goes to log in automatically - I believe that his main user name is the Administrator user renamed - and after restoring some settings it crashes as stated above. Guest is disabled so I can't log in as another user. I can't even boot the computer into Safe Mode - even the command prompt - as it crashes as above.
Things I've tried
1. Pulling out the memory and reinstalling it (I don't have other memory to swap it with)
2. Disconnecting the CDRW he installed recently (and did successfully use before this happened)
3. Using the recovery console to disable selected services when booting.
4. Last Known Good configuration (he had only one option there - I used that - I was scared to use the Default option on the basis that that would reset everything)
I think that LKG wouldn't help because essentially the computer booted successfully and only then crashes - in a process I can't prevent.
The services appear not to be an issue - if I hold the Shift key after the GUI has appeared I can get it to stop at the login. The system doesn't crash as long as it's not logged in so I suppose it's not the services (which would carry on loading)
I'm not so familiar with W2K so I don't know what approach is available to me.
Basically what I'd like to do is to create some sort of clean user situation such that nothing significant would run automatically. This might help us narrow down the problem. Right now we can't even log in enough to work out what program's causing the crash.
I had in mind to replace the Administrator's registry - or the general user registry if all are kept together - without having to affect the way the whole computer is set up. Ideally if we can go back to an old configuration and keep the current one to go back to later that would be best. I suppose that involves renaming a registry hive and going back to a stored one, using the recovery console, but only changing some of the hives not all.
What might I try that I haven't thought of? (or that I have)
Points will be awarded to a tip which gets us logged in without serious effects to configuration entailing reinstallation of OS/many programs.
