BSOD from pretty much anything

Have you booted into BIOS and tried to boot from USB that way?

It does take a long time, just persevere and let it run for eight passes.

I can't read your pictures.
Take your time and read through this Tutorial. It should help you get through the memory test the way it should be done.

RAM - Test with Memtest86+

While doing this test properly and your get a report of bad ram you can stop the test and report back to the good folks helping you.

I will go back to watching.

With regard to the memtest mate - unless I have missed something you might use these ditties of mine
SLOT CLEANING
Now as for the slots to clean them use a strip of old credit card (or any card thin enough some are better than others ) about 1/2 inch wide nip the corners off one end - preferably round them offhold a piece of thin lint free cloth over the end dab on some form of alcohol - isopropyl alcohol (what we swab the skin with before an injection) is good and GENTLY swipe along the slots.
This can also be done for the GPU slot/s and also the contacts of the sticks or cards - not the stick but some lint free cloth of course. See my pic for the sick but please be very gentle doing it if you are in any doubt - please ask before doing it but I use this all the time and have yet to damage anything
MEMTEST
The memtest you will need to make a bootable disk / stick and set the BIOS to boot from the optical or USB and it will take a fair time to run- some leave it overnight. see the attached document.

But one thing is very important you must let the test run for at least 8 passes any less and the findings are no good. Now if errors come up straight away then you can stop it - see my pics. Now if there are errors and you have more than one stick of RAM in then you will need to test each stick ie remove the sticks and replace stick 1 in slot 1 and test no errors do the same in slot 2 with stick 1 no errors then repeat the process with stick 2 - that will show up the faulty stick - the other thing is it could be a faulty slot but most unusual. With more than two sticks the process is even longer as one may realize.
It is a very lengthy and tedious process but worth it if you have errors.

As Laith says mat e because if it is set to floppy then it will look there first and it should search further but obviously yours isn't.

Personally I have always used a disk as it wastes less space say on a USB stick and can be kept as a dedicated boot (and is cheaper).
