Using win nt 4 server (sp 6a)

I have an annoying problem that I'm hoping it possible to cure - my nt
server is hardly ever used now but for one legacy system.

The problem is I had trouble trying to remove an ATI graphics driver which
didn't complete successfully, I now have to run nt in VGA mode, which isn't
a problem but I keep getting a an "error loading driver" on startup. After
pressing ESC about 30-40 times it eventually goes - noticed though if I end
task from the task manager it goes 1st time!

So I was wondering if/how to run a small app (batch file, Visual Basic
etc...) to end this task automatically on start up? - is this possible?

many thanks
