Hey i have a problem and it would be nice if you could help me with it.

So i installed the Mod from moddb.com, but after i played it for 30 minutes a RGL Error "Steam not running" appeared and my Laptop crashed. So i started M&B again, but the RGL Error was still appearing and still crashing my Laptop. So i had no other choice to deinstall it. After i did it, everything was normal again, i could play any game without the RGL error (The RGL Error also appeared in other Non-Steam/Steam games aswell) so then i tried the Steam version of the game. I started up M&B and when i got into the Muliplayer section M&B Crashed. I thought that this is something with the Steam Version, so i stopped playing it until i got a better PC. After Unsubscribing, i also thought everything would be like i deinstalled it from moddb. But the RGL Error was still appearing. I am so ♥♥♥♥♥♥ right now, because i cant figure out from where the f*** the RGL error is coming from now! 10 or 15 minutes is the maximum amount of time i can play ANY game before my Laptop will crash. How can i fix this?

Greetings,
