It's like this...
1. I start up the computer, the sound card installation is faulty.
2. I uninstall the sound card.
3. I run the Add Hardware wizard, thus reinstalling the sound card.
4. I shut down the computer.
5. Repeat 1-5.
I'm not sure if moving it to a new slot will work, but I'll try. If that doesn't work, I'll probably just reinstall Windows XP. Thanks anyway. ^^;
