First off, thanks for those wonderful instructions. They were very clear. I've attached the HJT logs and the AVG-AntiSpyware logs. The AVG-AS log is an old one. Basically, I entered safe mode and did an AVG-AS scan and saved the log. Then I remembered I had not revealed hidden files. So I redid all the scans and since nothing new showed up, I figured I might as well stick the old log. I've basically seen the BSoD twice today, which has never happened before.
