Look under System Tools - System Configuration. Go to the StartUp tab and check out the ticked items. I assumed that it was one of these applications in the startup that was conflicting. So, I unticked them and then I ticked the most important applications ie.. system registry, etc.... and rebooted. The error disappeared. Then I went back to the StartUp area and noticed that the more important applications had moved to the top of the order. So, I ticked the rest of the applications and rebooted the PC about 6 times and it seemed to get rid of the error.

So, I'm assuming that the order in which those startup applications were being loaded at startup was causing that conflict.

: I get the blue screen sometimes at startup, not all the time with the message above. I have a refurbished Dell Dimension L800r. I think it is a pent.3.
