I'm always one for trying to fix my computer myself - technically slightly above average, and logical at troubleshooting...but I am losing my patience with this one!! hardware in brief: Dell C521 - broadcom wirless card, nvidia geforce 6150 le graphics card, 3 gig of ram (2X1meg from crucial, and 2 x 512k default sticks that came with the machine). Long story short, I had vista, wiped it and put windows 7 32 bit version. Problem: intermittant BSOD with errors as per topic heading Tried: 1) memtest - ran it for 11hours, 6 passes, and no errors. 2) un/reinstalling windows 7 several times 3) reverting back to windows vista - issues with pixelling/garbagging when windows was powering up into profile so, the last point leads me to suspect graphics card problem.. however, I have never, and am unable to get winbdg.exe to read my dump file , as it asks for symbols. (i downloaded the pack and it had a zillion files in it, not sure which to pick. i tried a few, and the dump file still wouldn't work). I invite the best of the best, mac-daddy IT gurus to read the attached dump file and please please help me!! I've spent the last 2 weeks trying different things to sort this problem...argh!!!
