game start up crashing

I have 3,800 hrs in spaceengineers and know i can't get passed the startup screen. The report i get is my Graphics card has crashed due to over heating or over clocked. first I do not know how to over clock any thing on a computer ( US navy Diesel Tech). was playing just fine un till i was trying to make changes to the scenarios ( frost bit and learning to survive) then the game crashed. went back and undid what was do and now the game will not go passed the game startup screen. all drivers for graphics cards are up to date, tried to uninstalling and reinstalling the game but it still get error that my Graphics card has crashed. i have even asked around in the discord and did some of what the asked me to do but still get Your graphics cards has crashed. have a few steams i was looking forward to doing with SE but have to cancel them cause I can't get the game to work. also have tried to see if its was my cards but all other games I have work just fine and no crashes. I am using a MSI gaming Laptop with a NVIDA GTX 970M. please let me know what I am doing wrong and how to fix it so i can stop just watching other streamers play SE (Splitsie and W$stedspace) and play myself.
