League Black Screen After Champ Select (Game loads but no visual; just sound)

So, my LoL client is doing something quite interesting. So i was in a game two days ago on my new computer and everything was going fine EXCEPT that i was missing about 15% of my screen. I decided to try to go into settings while in game and i resized my screen to What I thought might be my actual screen size. After I did that my screen went black with the back light still on and me still able to move and hear sound but i couldn't see anything. My client has been like that since then. I will open it and everything will work including champion select but the second it loads into the game loading screen, the loading screen is black and when the game launches, that screen is black as well but i can still hear sound and move the champion around. I know i can move the champion because i hear the champions dialog when i click with my mouse. I have tried uninstall and Reinstalling the game, messing with the height and width in the gameconfig files for the in game setup, the windowed mode as well in the same area. I have checked my graphics card noted that it works fine. The only thing i haven't checked is my monitor. Maybe it's to old? I don't know.

Here are my Computer Specs: Intel Core i7 2600 CPU 3.40GHz 16 GB of Installed Memory SSD Sata Ultra Hard Drive NVIDIA GeForce GTX 275 64Bit operating system (League shows to be running on a 32Bit so not sure if that's the problem?) Fully Activated Windows 10 Pro

My Monitor specs Brand name is SANSUI Desktop Resolution: 1024 x 768 Active Signal Resolution: 1024 x 768 Refresh Rate: 60Hz Bit Depth: 8-Bit Color Format: RGB Color Range: Standard Dynamic Range (SDR) Side Note: The screen works fine in every other situation and way including with other games o i don't think it is the problem but who knows?

Alright Riot let's fix this! :D i am calling all help from anywhere. I have watched every YouTube video and tried everything i know to try. So I have attached proof that it is not my graphics card in the image showing a testing being done on my graphics card.
