When replacing my new Iwill xp333r motherboard, I got an especially cryptic blue screen of death from Windows XP SP1:

STOP C0000415: Unknown Hard Error

After searching the microsoft knowledge base and google, I couldn't find any information about this particular error. I called ATI (the manufacturer of my video card), and they said that the problem was due to a corrupted AGP driver. Below are the steps necessary for me to fix the STOP error. I'm putting them on the Web in the hopes that the next person who gets this error will find this page.

If this page helped you out, email me and let me know.
