Thanks for advance for you help.
Since you have already focused on the root cause and have had no improvement with updated drivers, etc., it is very likely the issue is caused by more than one conflict (or other damaged/corrupt/missing system files. If you have "added" Windows 7 Ultimate to this laptop, is it from a verified clean source? I would clean install Windows 7 from a trusted source, update your drivers and Windows to current. You will most likely find your BSOD issue is completely gone...then start adding your software and testing the network as each are completed after a reboot. You will either find a conflict/culprit that triggers the BSOD again, or the BSOD problem is gone for good, in such case the cause of your problem was 'system related' and fixed with your new clean install. Yes this will take a few hours, but I'm sure you already have many more hours vested in trying to fix this problem. IMHO start over with a clean install and your issue will be fixed for good.
