Have got a clients Server 2003 machine that kept blue screening on boot with either a Registry_Error or IRQL_Not Less... error (it was one of these each time it re-started)
We could boot into safe mode ok and it would stay stable so i disabled all the services and processes with the aim of re-enabling them one by one but even though these were all disabled it still blue screened when booted up normally.
I ran chkdsk and it cleared a lot of errors up and now am at the stage where if i boot into safe mode it stays on but it just gives a black screen with 'safe mode' on it. I can Ctrl Alt Del but it shows nothing running and so i can't do anything apart from shut it down.
If i boot into normal stage then it'll either Blue screen or just hang on Applying Computer Settings.
This is a main DC with Exchange and is the only server they have and so contains everything.
Can you do an overwrite install on Server 2003 like you can in XP and if so what will this do ?
Apart from that any help would be great.
P.S. nothing has been addded or changed for this to happen.
