Hi Guys,

I fix computers nearly every day but for some reason i find my self to be stuck on this one! Took a computer in (working from home) with the BSOD, continious restart - got the error to be a winlogon.exe fatal system error with STOP 0x135.

I have done the following:

1. Carried out chkdisk with /p /r - it found problems and repaired
2. Cloned the HDD onto another HDD to eliminate HDD issues, still occured which confirmed its an OS error
3. Directly copied a new winlogon.exe from the XP Home CD to the C:\windows\system32 folder, copied ok and start up now looks like it works whereas you see the keyboard lights flash and usb mouse light up and the XP loading finishes just before the logon screen the BSOD comes up.
4. Carried out all memory, MB, graphics card test etc
5. Reset CMOS
6. Tried to repair the windows xp installation
7. Tried to re-install windows xp but with a new windows folder, naming the old one windows.old, still restarted with BSOD with same error

What else can i do? I really can't format the hard drive as clients telephone system is on the hard drive and programs installed.

Is this a registry issue?

Oh, sorry i can't boot into safe mode - i get further but all i see is the windows screen & the mouse no option to login to the accounts, just stops but don't freeze as the keyboard still lights up CAPS etc.

Any help would be much appreciated.

Thank You!

You do really need to keep that copy, until things are sorted out.

"Is this a registry issue?"
Could be that or an infection or a corrupt program.

You have a tough one here & you have done everything right.

I only thing left to try, that I can think of at this stage, is a rescue program, here is all my info on those type of programs.

Avira AntiVir Rescue System

AVG Rescue CD

Hi John, thanks for your reply.

I have a backup of all the docs etc on the hard drive, being i used a ide/sata/pata to usb and cloned the hdd onto another one and taking the docs off onto another hdd of my workshop computer, best to be safe!

The thing here is the docs are not a great worry for the client, they have that telephone system and all saved information is in those files and cannot simply be imported into a new installation, for example you can export and import from Outlook express - you have no option on the software for the tel system.

The reason for the clone was to try a fix on the windows folder but with no avail.

I tell you something i have not tried which i will tonight is a virus scan as you said!
If its a corrupt program, i know there is a list somewhere that details events, do you happen to know where this is located? as i will plug it back into the workshop pc and locate it from there.

Been away medievil2003, here if needed is what you can use.

HOW TO: View and Manage Event Logs in Event Viewer in Windows XP
Start > Run, copy & paste > eventvwr.msc /s & press Enter.
Scroll down to the last time your computer crashed and it should tell you what device/driver caused the problem?
Event Log Explorer
