HELP everytime i try to load up a level game crashes.

i was playing on gridmap and then all the sudden my pc just turned off and wouldnt turn back on for like 20 minutes then i go back on and start up beamng and then everytime i tried to load up any map it does not work. help. what do i do? i already uninstalled and reinstalled then restarted my computer. so what else could i do?

 

welp. my pc specs arent that good. its a laptop. and yes it did overheat. i felt the bottom and it was SUPER hot. and what can i do because this game used to work perfectly fine?

 

I'm not an expert with computers but, it could maybe help if you got some new fans or if you could open your windows (i mean real windows not your operating system )
