Having the same problem since one month as well; I'm guessing it has something to do with the new engines/drivers they implemented, or maybe it's the NVIDIA drivers themselves, wouldn't be the first time they're causing problems like this... I still remember some months ago, when latest drivers caused SWTOR, and ONLY Swtor, to have flickering black spots all over characters.
This problem doesn't happen with other games, except SWTOR; I did get some weird crash with Mass Effect 2 which resulted in another impossible-to-close black screen, so I'm guessing maybe it's all origin games, or something with their engines?
Difference is, I can alt tab during the game with no problem; the issue appears only after closing it... it's like the screen freezes, but I know for sure computer is working, because I can bring up task manager and use my windows key to bring up menu (I restart from there everytime, there's no other workaround so far to get rid impossible-to-close black screen), I just can't keep em on top, black screen is always on top.
Anyways, overly annoying, and nothing to be found on forums or googling; really hope someone would take notice of this and tell us poor soul who aren't programmers by trade how to solve this... pretty please with a cherry on top?
Proxos posted an link how to do an dxdiag and post it here.
Do that and we might be able to help you.
It's apparently a wide spread issue due to 5.0 Official Forum Link
Thanks everyone for your time, now fingers crossed for the higher ups to find a solution...
Also now listed in the known issues sticky , this is being investigated back in the studio
However this is just on closing of the game and just occured with 5.0
If you have had this issue for months then you have a different issue
