Tried the suggestions, as well as going out to the Dell site to get list of any other vendor recommended updates. Dell even had a BIOS update out there. Unfortunately, when I applied this I lost internet for a few days before I was able to use my wife's iPad to find a fix.
So, things had been running ok for a bit - I even thought the BSODs had stopped as the wife hadn't complained.
Well now they're back again - I've BSODed 3 times just trying to get this file created. Any other recommendations? Do I have bad memory or GPU? (By the way, the previous link talked about NVIDIA, but we've got ATI.)
