Thanks all, for the words of encouragement and advice. :) I think I just might open this thing up and check it over. It's less than 2 years old though....... This happened once before...right after I installed Windows Media Player 7. Late last night I did it again, figuring it ought to be stable by now. I guess not, or at least, I guess there's something about MY PC that it doesn't like. Anyhow, I'm reinstalling software, and trying to locate all the stuff I've been putting on CD. For as much as I had backed up, I can't believe how much I didn't have backed up, which unfortunately is almost all of the models I've downloaded and built, except for the stuff I paid for, like Zygote/DAZ characters for Poser. But everything else is gone. All the cool models I found over this past year. :( Oh well... I'll get over it. Thanks again, everyone. :)
