Your problems could stem from InCD conflicts with the IDE, AGP and other drivers which you have just installed. So please provide as much information as you can about these drivers. What are the brands and models of the new graphic card and your motherboard?
To identify such drivers, we need information about your IOSUBSYS directory, ASPI layers, and possibly extracts from Nero log file in a format similar to that in
http://www.cdrlabs.com/phpBB/viewtopic. ... 7767#47767
First, in an MS-DOS Prompt window, type "cd c:\windows\system\iosubsys" (without quotes) and Enter, then "dir>c:\iosubsys.txt" and Enter, thus listing your IOSUBSYS directory in the file C:\iosubsys.txt. Also tell us if you have ever installed external devices on your box, such as burners, Iomega drives, etc.
Second, tell us what Nero InfoTool says about ASPI (system and Nero).
Third, look in C:\Program Files\Ahead\Nero for NeroHistory.log. Each session in this log file starts with the header
====== *** Nero-Burning Rom, History File *** ======
and is divided into paragraphs by empty lines; at the beginning of paragraph 5 you will see the date of the session (e.g., 28.2.2003). Each session is quite long, but we only need the initial info section (ending with "Wizard: Off or On") and the final "Existing drivers" section. We need these two extracts from an older session produced before your drivers changed, and from the latest session run after the changes (just simulate a burn if you don't have it).
And of course tell us about your versions of Nero and InCD, and other burning programs and plugins (e.g., from WMP).
