system error message when using autocad, need help!!

I have logitech cordless mouse and keyboard set up for my laptop, when using
autocad I can be happily working for hours then all of a sudden the lights
go out on the receiver unit for the mouse and keyboard so I get no use of
either then within 10 seconds my whole system crashes (I usually notice this
quite quickly so have time to save on autocad using the laptop keyboard,
which still works), I get a blue dos screen with loads of white text on,
look below to see what this error message says. I always use the keyboard
and mouse and only have this problem when using autocad. I have the latest
drivers for the keyboard and mouse and because this problem is only when
using autocad logitech can't
help me, they have never heard of this problem, Autodesk aren't much help
either. my system is p4 2.5Ghz, 1GB Ram, 64MB graphics, running windows xp
pro, this problem happens on both autocad r14 and 2004.

any help would be greatly appreciated,

TIA
Mark
