BSOD

Hi guys, having massive problems with my pc and am getting 4-5 BSOD every day. I've pasted the latest log below, anyone have any ideas what's causing it?

I tried installing the latest verson of the drivers for my graphics card (AMD radeon HD 6900 series) but it crashed minutes after I did that so that wasn't the problem!

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.256.1

Additional information about the problem:

BCP2: 000000000000000D
BCP3: 0000000000000008

Files that help describe the problem:
C:\Windows\Minidump\040812-43773-01.dmp
C:\Windows\Temp\WER-52634-0.sysdata.xml

You need to post the .dmp files. That way people can see a possible problem. Zip up the C:\Windows\Minidump\ directory and post it.

Ah ok sure thing, here we go:

I had a quick look at the last 4 mini dumps. It points to something different each time. So as a start, set you motherboard BIOS on the most conservative setting. Then start testing you RAM. (Memtest86+ Memory Testing)

BTW It will help us here if you list your hardware or just update that part of your profile.

Hope this helps.

Thanks a lot, I've downloaded that programme and stuck it on a disk, gonna do a few runs through and see if it finds anything - I've already tried the built-in Windows memory diagnostic tool but that didn't reveal any problems.

The hardware I have is:

Graphics card - AMD Radeon HD 6900
Processor - i7 960 3.2Gb overclocked to 4Gb (bought an overclocked bundle package)
Motherboard Gigabyte - G1.Guerilla
6Gb DDR 3 RAM

Thanks for any help you can offer!

Ah, what do you mean by setting my motherboard to the most conservative setting? Also how can I tell what setting I have on it right now and do you know how I would change it?
