BSOD caused by graphic card drivers, but not convinced

Hi all,

I have the following computer
CPU : Intel® Core™ i5-4590 CPU @ 3.30GHz
Motherboard : MSI B85-G43 GAMING (MS-7816) - latest device drivers
32gb ram
graphics card : AMD Radeon R9 270 - latest device drivers
Hard drives : 3 (one main and 2 back ups)
which I use for video editing (work) and playing the latest star wars battlefront (play).

But there is always something wrong, I getting BSOD every 12-36 hours. Now that I have finished a major video editing project I can try to work out what is wrong; I tried a few things but what fixed it was removing the graphic card device drivers and using the default drivers. But that means I don't get the full use out of a $300 video card!

Now before everyone assumes that I have fixed the problem I must point out what was happening before.
When I had the graphics card drivers installed I used to do some funny things to get the computer to work - I used to unplug the DVD drive, unplug/plug in other hard drives (yes, plugging a second hard drive back in used to get the computer working for 2 days), swapping ram chips, taking out ram chips (which I was hesitant to do as I needed them!).
I have tried each ram chip one at a time and they are not the problem.

So what could be causing all these problems? Is the motherboard not handling it all? Is it really just the video card and I need to get another?
Is there a program I could download to check all my hardware to see if they are working correctly?

Here's a conundrum, I own a legal copy of windows 7 Ultimate - but it doesn't work. I had that much trouble with it I ended up installing a pirated version.

Here's a photo of a legally bought copy that I tried to install but had even more problems and BSOD than I do now.

I'm not trying to be difficult but I did install this and it passed the genuine activation but I had problems from day one with installing device drivers, some hardware wouldn't work anymore, BSOD was daily; and then the final straw was when, after two months, genuine activation failed

With this pirated version I only have a quarter of the problems.

Is there a way of using my genuine key to convert the running OS? Or do I need to fresh re-install? I don't want to reinstall if possible
