Creo crashes whenever i start a part or open assembly
So i was making 2D drawings when my screen suddenly went black, after waiting my pc started up again and my desktop looked funny as in my pictograms got bigger ec, then when i opend creo evrything is fine untill i open a assembly. After restarting i tried making a new part but it starts fine till i try something and then it just freezes. How can i fix this? i looked around for a solution but im not a techy guy.
It freezes as soon as i select to see the planes
