Plutonium

Hi whatever I seem to do Black Ops 1 crashes constantly, can't load a single multiplayer, zombies or campaign level. And it often shuts down on startup.
crash report give Exception Code: 0xC0000005
Exception Address: 0x0097126C.
These crashes happen with or without plutonium. I have reinstalled multiple times, tried countless fixes.
Drivers are all up to date, only using windows defender.
Please help/
