Random BSOD and various problems - hardware issues?

Hi, sorry for disappearing but I was quite busy and my computer started working again. I really have no idea why, I didn't do anything.
Not a single crash in three days, and it's been working for four days. I can't do a Startup Repair as the system doesn't detect any errors (but I believe I did try for at least three times in a row). I reinstalled Avira, and will reinstall Steam if everything is find. I do find my computer a little slow though, in regards to its specs.

There was a Windows Update though, I'm guessing it's because I went back to previous settings (which didn't help with the crashes). Here are the latest dump files. I haven't had a BSOD these last five days, only one or two screen freezes.

Thank you again for your time.

Nope, just one or two weird screen freezes that look like this : https://communities.intel.com/servle.../Intel+Nuc.jpg (only more abstract).

Will wait and report back if I get a BSOD again - in the meantime, do you have any links where I could learn more about Windows 7 optimizations and the like? I'd be nice to understand more about what I'm currently doing.

Until then, I will hope and burn candles till the next summer solstice.
