Well, I tried setting the audio acceleration down one level, and it worked sort of well for two days. It would still crash, even harder than before, but after about two hours. It would freeze in-game and I would actually have to turn the computer off (not just reset) and when it came back up, the screen resolution was 800x600 at login then would change to 1600 x 1200 at the desktop. Very odd. However, yesterday and today it went back to the old ddhelp error. I checked the audio acceleration settings and they were still at the one notch down setting.
Maybe I should just rebuild the computer again this weekend. Maybe I did something wrong last time. However, I rebuild computers all of the time, so I think I know what I'm doing by now. Glad I kept all of the recent drivers.
Any other things I should try before I get started? I'll start Sunday afternoon so if you have one you have until then to voice it.
