Computer problem seemingly solved (for real this time)

It appears that after all my screwing around with wireless internet adapters and Norton Utilities, my recent BSOD issues can be traced back to an updated audio driver I installed some time ago. While searching for my Windows 7 DVD, I happened upon the driver DVD that came with my motherboard. For a goof I threw it into the computer and reinstalled the OEM driver. That was last week and I haven't had a BSOD since. I also finally got around to cleaning all the dust out of my machine (the CPU cooler was packed solid), which didn't hurt things either.

Happy days.
