When I 1st installed RC1, it froze up on the reboot. I played around with it for hours without any problems, but it froze up again on the shutdown. And when I say "froze", I mean it got to the shutdown screen with the small "spinner" in the center & the spinner simply stopped. Ctrl-Alt-Del does nothing....I either have to shutdown via the power switch or reboot via the reset button. I googled the problem but came up empty. I've tried rebooting or shutting down several times & the problem is consistently there. Anyone else experience this? Also, how much disk space does this hog use? I didn't check after the initial install, but all I've added is AVG & my printer driver & I've used 9.1GB. While I'm at it, I ran across the following when looking for an answer to my problem...IMO, some very vailid criticisms: http://www.winsupersite.com/showcase/winvista_rc1_worst.asp

This is the first I have hear of it but I do know that when I worked at a big computer place we would have issues with boards on new releases. Even if the board ran the old OS the new OS found firmware or hardware that while in all specs correct it would fail. There are just millions of parts on millions of boards out there. One little bit wrong in the right place can do what you have. You now see the reason for "Vista" ready as was "XP" ready. The boards are tested to the current release so that shouldn't happen as much.

Just in case, here's my specs: - Shuttle AN35N-ULTRA Motherboard - Sempron 2500+ @ 1.94GHz (10.5 x 185) - 1.25GB PC2700 (512+512+256) @ 185MHz running in dual channel mode (yes, DC mode) - Radeon 9550 128MB/128-bit - 80GB WDC ATA100 - 350W Super-Flower PSU This is my secondary machine which has been running XP Pro without any problems.

I recall posting that criticism in addition to some of Vista's good sides few days. Do you have Aero enabled? If you do, disable it and see if that help any.

"I recall posting that criticism..." Sorry about that. I'd seen you post but only checked out the "pro" side. I'll see if Aero makes a difference & report back. Thanks.

No worries. You probably didn't check the "cons" because you expected something like a winner from M$ and you should - 5yrs of R&D.

I disabled Aero & there was no difference...still freezes on the shutdown screen. I also disconnected my printer & uninstalled the software & AVG wasn't initializing at bootup so I uninstalled that as well. It made no difference. The only thing I have left on the uninstall list is Adobe Flash Player 9.
