I just put together a new computer for our trailer. Intel BG33BU motherboard, Intel E 8400 CPU, 2 GB of Kingston 6400 DDR2 memory, 250 GB Seagate HD and a Sony DVD recorder. After installing every thing in a Antec case I tried to load Windows XP Media Center Edition. On the third try it loaded. After many attempts to load drivers and other software I thought that may be the Sony DVD was bad and changed it out. No joy, same thing nothing will load to the program. Oh, in the paper work that came with the motherboard I was told that if I wasn't going to load Vista I had to change SATA to IDE in BIOS. I did that be for I started to load XP. I decided to try and load vista to see if it would work. Vista loaded but it wouldn't start up. I did a repair from the disk and now most things seem to work. One thing that is wrong is I use a program that is called Net Waiting it wont work or let me uninstall it. I use it on the other computers and it works with them and they have Vista. I don't understand why XP wont work on this computer or why Net Waiting wont work with Vista on this computer. I relay wonted to use XP on this computer I mean I already paid for it. If I have to keep Vista on it I will have to go pick up a new copy be for the 30 days are up. This computer is meant to be a Media PC for our travail trailer. I have a WinTV card to install after I decide the way to go. Any thoughts on what is wrong or how to fix it?
