Apparently my laptop was temporaly fixed again. Tech guy did the "oh, I don't know what's wrong with it, I'll try to look at it the LAST time and then look for someone else to fix it" card again and 'fixed' it (inb4 something goes wrong with bios again and I'll need him again to reset it) despite me telling him that it crashed the same exact way as the first time and it had something to do with bios back then so yeah, I better earn some money with this garbage and buy a new one before it crashes like that again.

Maybe I'm too hard on a tech guy, maybe there was a different reason behind this crash after all. But either way I need a job. And prefereably a new laptop or maybe a desktop instead of it.
