So I bought this about a month or so ago and a 5.1 Surround Sound system. I installed the card and drivers. Everything was sexy. About 3 days ago I opened my DMZ to test something and forgot to close it. Thus my computer became a pincushion for all the lovely crap out there. I couldn't get windows to work(stuck at loading bar for ever) so I tried to repair. When I tried that my disc couldn't load 3 .sys or ini files. I don't remember which. So I said eff it and I did a reformat. Windows XP Home works fine. I installed my intel upgraded chip, video drivers. Every single driver except my X-Fi drivers. Whenever I try to install it either gets stuck at 49% or 69% depending on options I select. I tried another reformat. In-case a low level reformat. Tried installing in safe mode. I tried installing before everything but windows and after. After restarting etc...My nerd friends can't think of it. I can't think of it. Geek Squad(I work at best buy) can't think of what could be wrong, unless I wanna spend 120$ for them to fix it. I also tried installing other sound blaster drivers(i had a sound blaster before the x-fi one before.) didn't work. And I can't select the sound card in device manager. I could try moving it down a PCI slot..but I doubt that will work. Any help is greatly appreiciated. I'm going to post this in OS forums in case it might be XP related. Thanks again.
