Hi there...
I had this problem.
All i did was to re-install mobo drivers..i.e if u have an
Via chip set,then get them from ya mobo makers
site. And that should do the trick...
UPDATE...
looks like i will have to do a re-format..
some of mine(not all)burning progs wont work..
will post back..

OK...re-formated installed XP all is ok now...
