Folks, Few weeks back, the mobo on my HP xw8200 blew up. Nothing else was wrong, but when ordering the "new" mobo for it, I also got more correct RAM and two 3.6GHz Xeon CPUs. Got the guts back into the pc and fired it up. I almost cried when I saw the Windows 7 logo appear. AWESOME!!! Now before the mobo blew up, I had no issues connecting to the HTPC I built with Windows 7 Ultimate to share movies and such. Afterwards, Media Center hangs when trying to access the shared movie and music libraries. I expected that to occur somewhat with the music library since it is HUGE (and growing), plus I am running a 100Base-T network, but I never had issues with movies at all... Any ideas? I am thinking I need to rebuild the pc from the ground up and let Windows 7 recognize everything on the "new" mobo. Is this a correct thing to do?
