It's the latest version, and yes it worked fine before. The uninstall was pretty much all trial software like norton, skype, aol, things of this nature. This was all stuff pre installed as a trial basis by Sony. I am thinking it's a compatability issue with the dvd r at this point and not the software,,, maybe a reference driver attached to one of the things i removed. I have spotted lots of threads on problems with this matshita uj 8505 drive and Vista... some stating it's not Vista compliant. But it worked b4.
We'll try a restore and see if that solves it, but I it's been running so much smoother w/o all the extras that i wanted to avoid that. ( except for the drive of course
