Well, i must say I was like :hmm: for some time. But I rarely have any probs and it runs very stable. Also the new NV drivers are very stable, so its getting there. Occasionally I have a prob like the above, but if you dig on the net you are sure to find a solution. Maybe not for every one but I am pretty satisfied with VISTA...it can only get better
Oh I forgot, you have to do all above stuff using " (Left Click) Run as Administrator"
