So I'm just going to start off by saying I'm no expert at all so this might be simple but I don't know...so I'm going to try to provide as much info as possible. Having some problems with my computer (XP Pro SP2). A couple weeks ago I upgraded my motherboard, CPU, video board, and RAM using http://www.theeldergeek.com/replace_motherboard.htm <<< those instructions. Everything went great and I haven't noticed any problems until last night when I wanted to connect to my Xbox360 for the media sharing (which I have been able to do before). I couldn't get it to connect with WMP11 so I used that Zune software (all the while following Microsoft's instructions) to the point where it asked me to select a device to share to...there was nothing to select in the box so that got me thinking there was a network problem. Did some looking around and noticed I couldn't see any of the other computers on my LAN at home (normally I can). I thought that was weird so I then tried to see if I even had my printers (I don't) that are connected through a computer that acts as our print server (everything is setup as a workgroup). All the other computers in the house can see each other and the printers... So after all that I was frustrated and didn't know what to try to I figured I'd just restart and see if magically everything would work...but when I went to the restart thing there was a Microsoft update shield on the upper right corner of the shut down button saying there were updates to install and they would be installed when I shut down. So I tried that and it said I had 1 of 89 updates being installed with the little periods moving next to it but in the middle of that Windows shut down. I started everything back up and noticed the yellow shield in the tray indicating there were updates to be installed and clicked on it and they started the installation process but then stopped and it said there were updates that could not be installed and listed them (security updates, WMP 11 updates, etc). Soooo WTF is going on...I have no idea what to do?!
