All games having random crashes :(

Okay so I’m having a problem at the moment with all my games, at random times while playing it crashes and that window thing saying this game has stopped comes up and fails to find problem. All my drivers are up to date and I tried a system restore so not sure what the problem is. I’ve looked at the event viewer thing but not sure what to do now, mostly been playing Final fantasy online lately so most screens of that event crash but a few of van helsing as well. It happens with others but cna find in event log >.>
