Struggling with BSOD

[Ronnzen]

Hi! My english isnt the best, but ill try to explain.

The BSOD suddenly pops up whenever it wants, and I get it alot. Im not a computer man, so I dont understand what to read, or what to do. But I hope you guys can figure out the problem, or atleast get me closer to a solution. Ill add the minidump file here, and hope for quick response on the problem. Just ask me if you have any questions regarding my computer please. Ill answer as fast as I possibly can.

I also noticed a file named MEMORY.DMP which was 211 568kb, should I upload this file too? Or is it something else?
