Interestingly I'm getting almost the same message:
instruction at 0x7c910e03
but referenced memory is 0x000000fe
My computer isn't a dell it's an MSI board with an AMD Sempron processor.
I get the error when I run Nero Vision (crashes 2 hours into a video conversion).
I tried 3 high quality memory modules and a memory stress test.
Changing modules doesn't make a difference.
The stress test didn't pick up a problem with any of the modules.
I have put in modules one at a time and together... with similar results.
I think it's a software problem. Whatever program references that instruction is stuffing up. In my case it's Nero but only when it's using Nero Vision. The Nero bug fixes refer to problems like this... but I'm not sure if they've fixed all the bugs yet.
In your case it sounds like something else... but perhaps it's related to Nero?
