My windows 8.1 computer is constantly crashing

[Miolini]

Hello
Recently (the past 4-5 days) my home built windows 8.1 stationary computer have been crashing allot seemingly randomly. Other weird stuff have also happened such as pages randomly getting "aw, snap!" errors and games crashing such as League of Legends and DotA2. The errors i've gotten from the blue screens are the following: "reference_by_pointer_crash" "memory_management" "system_service_exception" "dpc_watchdog_violation"and its often different. Im not to familiar with stuff like this and this made me kind of uneasy as i couldn't find a solution on any forums. Ive also reset my computer from scratch and reinstalled windows. It did create 3 new partitions when i reinstalled it so that could be something. It is still crashing and i'm currently testing if its one of my rams that is causing it. Ive also done virus scans and malware scans and also done a hardrive scan from windows control panel and i haven't found anything.

My hardrive is a seagate barracuda st2000dm001
Ram are 2 ballistix sport on 4gb each

I see. This problem is not connected to a windows update though. Andi dont know how that could explain the other errors and or the crashing when playin games ....
