Can you explain thata again with easier words becuse I dont have the best english, and btw when I send my PC to a check in stores they cant find the issue becuse it never crashes for them becuse its so random.. it can work for few days perfect and then suddenly freez/crash...
 
Ok you say now that this happens randomly. It works for days and then it crashes, correct? If so then it can be either the card or your ram causing the issue. I do not think BIOS has anything to do with this.
Run memtest on the ram to eliminate it as the culprit. http://memtest.org/

btw when my pc crashes the video card is not geting detected i think. when I restart my PC after a crash the screen dosent even do anything when I do so, so when i switch to mother board it dose detect it...

I dont have any spares lol and it didnt crashed yet with the mother board so idk mostly i use the mother board for 30 min and then try to restart and swap back (my PC crashes mostly in games sometimes I have an long freez and then it comes back like nothing happend...)
