Bsod

This problem has happened twice. Before I tried to check all my drivers and updated the Microsoft Miniport WiFi adaptor and for some reason that satisfied the computer, but then it BSOD-ed a week later. Check disked and fixed a few things but that didn't change the BSOD. The BSOD suggested updating the BIOS but the updater I downloaded wouldn't run in Safe Mode. I can't get the video card driver update to work either in safe mode.

It's Windows 7 Home Premium 64 bit operating systems.
Gateway F6860
bios: American Megatrends inc. p01-a4, 5/2/2011 smbios ver 2.6

The BSOD additional details has varied some. Here is the info from one of the last times.

BCCode: 1e
BCP1: FFFFFFFFC0000005
BCP2: FFFFF88003A874A0
BCP3: 0000000000000000
BCP4: 0000000000000000

What other details should I provide?
