Blue Screen (of Death) during full backup

Tuesday I finally had my system running like I wanted it to. I run Home Premium 64 bit SP1. So I thought I should make a full backup of of all my documents on the internal harddisk and the external harddisk as well. I did this with the built-in backup centre. The backup was made to DVD's. The first attempt failed. My wife was working on her account, while backup was running on my account. It just stopped for an unknown reason.
I started another full backup and got a blue screen when changing DVD's. The Problems and Solutions function did'nt come up with a solution. This happened three times in total. Today I finally finished this backup (it picks up where it left of). My system is running fine otherwise. My harddisk is fine. HDTune doesnt show any bad sectors. I suspect it's a driver problem of sorts, but i'd like to have a definitive answer.Anyone able to help me?
Thanks in advance!

Please check your Power settings, set it to performance. And Check your Reliability monitor for yellow Icons. That should tell you why you had a blue screen

Thanks Caretaker for your extremely quick answer. As I'm a newbie, I'm going to ask a question that befits my status. Where do I find the Reliability monitor?

Found it, sorry my earlier question was too quick. Having trouble putting a printscreen in this post. maybe a direct link works

I can add the minidumps if you like.
These codes don't make sense to me.
Thanks again!

Click on to the day it happened and it should tell you why it did.

Under type of fault it states the the OS stopped working. Under details it displays a bunch of codes of which I can't make anything. (0x000000e3 and such) I seem to have been able to put the picture in my post...
