I couldn't get the game to BSOD on my wife's system, so I switched back to my box to try ti figure out what the heck was going on.
Well, last night I had something weird happen. The game locked up and froze my video card, making my max resolution 800 x 600 and my max colors set to 4 bit. Took me some fanagling, but managed to get a true shut down (I hate pulling the plug on a system crash). When I tried to restart, I got nothing. Black screen, no Windows, no BIOS initialization... nothing.
The last time I had this happen was when I built my last computer. The problem there was that the system refused to recognize the video card, so after I got the card set up, the next time I'd boot up it would just black screen.
Working on a hunch, I blew my CMOS and rebooted. This set all my BIOS settings back to the factory defaults. I went into my BIOS to set the time up, but left everything else alone.
Anyway, long story short, after doing this I was able to play for 4 straight hours without a blue screen. I had some screen flashing that I had to restart the game for, but that was it. It was the first time since switching to Beta v2 that I was able to play for more than an hour or so without a BSOD.
Was the problem my BIOS settings? My AGP settings may have been funky to the point that it was causing the BSOD. I was an early adopter of the Radeon 9700 Pro, which had some issues back before they got the drivers working well. The issues required me to do some funky AGP settings to get it to work properly (the settings were spelled out by ATI as a work-around back in the day, so this wasn't something unique to my system).
This may not have fixed the problem, but last night was encouraging. I'll spend a couple of hours tonight in game (oh no!) and see what happens.
