Windows Vista
Remember my post way back about Vista? Well, I have reinstalled Vista and I have ( again ) experenced no comapatablity problems. But, this time I did a “Upgrade” install of Vista from XP Pro. On the first boot everything looked normal untill I tried to reboot or shutdown, It would freeze ( no BSOD ) every time and I ended up recreating my user account, this fixed it. Thats was probaly the only major issue during the upgrade, and everything is fine today as I am typing this post on that very same computer. Also, I’m going to hold off on SP1 untill I get more than 1GB of RAM 
Again, I have had no BSODs on this Dell with Windows Vista on it, it all depends on your hardware. If you get a chance check out my Flickr Account in a few days to see pictures of the Dell’s case mod. More posts soon, Check back!
