Hi, I have a PC (Dell XPS Gen 3) running Win XP that is experiencing intermittent blue screen errors. The user reports that they've been occuring overnight when the computer isn't in use. It's happening on average once every 2 weeks or so. We've tried the general troubleshooting steps in the "Before posting your minidumps, please read this" thread, including memtest (which didn't report any problems), but the blue screens are still occuring. Would anyone here be able to take a look through these. Any help would be much appreciated. Thanks!
