First and second are blaming DirectX and indicating Steam is involved, let's see if other drivers come up,
Third, not being Driver Verifier caused, is hardware caused. RAM is most likely, next hard drive, with Directx mentioned above it also implicates the graphic card.
Forth, Also hardware blamed, verifier enabled, points to RAM, including graphics card.
Fifth, is directly blaming Steam. Info found mentions that running other programs while gaming can cause this crash, due to the resources required.
Sixth, blaming hardware, mentions MSE.
Seventh, same as the forth.
Eighth, similar to the fifth, blaming Firefox.

Either Steam is crashing or you have hardware that is crashing Steam.
Run SeaTools extended test.
If SeaTools and memtest86+ passes, it's leaving the mother board as about all that's left.
You can try a OS Clean install, before we blame the motherboard.
