Random BSOD - suspected hardware related minidump attached

Hello all, I am new here but am so far extremely impressed with the members know how and courtesy in helping others.

For quite some time now I have been experiencing blue screen crashes randomly.

I have little programs installed and most regularly use the computer for playing WarThunder and occasionally Battlefield 4. Although sometimes the BSOD occurs just browsing the web, or even at idle! There is no frequency attached to the issue with sometimes hours or sometimes days passing without incident.

It is also worth mentioning that quite often after a crash, my machine will just go into an infinite boot loop without ever reaching POST or BIOS. This continues until I cut the power and restart, in which case it may do the same again an indefinite amount of times, or just spring into life as normal.

I have not tried any overclocking and temperature monitoring software shows perfectly acceptable readings throughout.

The crashes got so bad about 6 months ago that I gave up using the machine, I would now like to get to the bottom of the issue so have started the fault finding process.

I will attach the minidump files as far back as they go (as I said, some months now).

If there is any further resources I could share to help anyone who knows what they are looking for I would be more than happy.

Lastly, I am semi proficient in computing and my machine is home built. I accept switching out hardware may be needed.

EDIT: I have used Command Prompt to run a SFC /scannow but it has found no integrity violations.

I am just trying to successfully run a DM Log which I will post next.
