random BSODs (1A, 1E, 0A)

hello,
i have built a new PC like 1 month ago, i also overclocked my i5-3570k, but it is a stable overclock i guess since prime95 ran for 8 hours without any error. I started getting these BSODs recently, first 2 weeks after i overclocked it, there was no BSOD whatsoever, after i started getting BSODs i lowered my OC as well but it hasnt helped. Im already desperate due to the fact that this PC cost me a lot of money and its already broken I also checked both of my RAMs with memtest separately but there was no error found, i have no clue where could be a problem, please guys, help me.

just got another BSOD, this time it was 0x0000000A again

i also think theres a problem with collecting my dump files, coz i cant see it in my "seven forums" folder nor in my windows folder, do i have to turn dump collecting on somehow or can u see dump files in the folder i posted?

edit: as i googled i didnt have small dumps (256kb) enabled so when i get next BSOD i should already have my minidumps

edit2: i found one tool to analyze these minidumps and it analyzed one of my previous BSODs as follows:
