My Dell M6500 and Performance Upgrades

This month I’ll be switching over from a Dell M4400 to a Dell M6500. Samantha is rocking it out with a Dell Vostro V130.

HOW TO do a (relatively) clean install using Windows 7 Upgrade DVD

In the past it seemed like you could do a straight-up clean Windows 7 install using an upgrade DVD on a new PC. Last night we tried a clean install on my buddy’s new PC, using just such a Win7 x64 “Family Pack” upgrade DVD, and everything installed just fine (selecting “custom install” instead of upgrade install). BUT, after booting the Windows product key wasn’t accepted… So, the solution was #1 to go ahead into Windows (by not entering the
