Well guys, to make it short, I decided to abandon Mint at least until it comes to the wise decision of abandoning Ubuntu and moving to something stabler, like Debian stable instead.
Following Ubuntu's buggy pattern and being based on it made me realise it isn't really an option for me. It's just rebranded Ubuntu, and even though the updater prevents crashes due to it omitting kernel updates, every new release is still based on Ubuntu and therefore inhabits the kernel it uses as well, so what didn't work on Ubuntu for me naturally didn't work on Mint as well and I got tired of it.
My last resort was LMDE, which also crashed all of a sudden so I see no point in using Mint, unless the developers decide to either follow Debian stable or something else, or become independent.
Thanks though for all your time and effort put into this project. For some it works, for some not and generally an ideal operating system supports all the hardware. If Debian can do it, some others as well, or support most hardware and even older ones or discontinued ones, Mint could do as well.
Ubuntu simply has the bad habbit of blacklisting old hardware, making things that used to work stop working, which is the dumbest idea ever to cross a developers mind and I wonder how could someone possibly come to a conclusion like that and vote on such an idea to pass.
