So, I have this computer. Every sound card I install in it, using the correct drivers, will not work. I'm not sure what is causing this issue. Error: Windows cannot load the device driver for this hardware. The driver may be missing or corrupt. I have used the original driver cd, and have tried downloading the correct driver from the internet. Yes, I do have the correct driver. It's running XP, and is an hp a1550y. If I can get the onboard card to work, it would be great! Everything else works fine.
