I suggest you seek help from an specialist

I don't work for EA

@samiam790
So this is Origin or the game problem despite the Windows report
Have you tried to repair the game in Origin?
Another method - uninstal Origin manually in add / remove programs option Use Ccleaner.

Download the latest Origin version

One  more solution

Reinstal your graphic card drivers even if you have the newest one instal it once more.  

Sometimes driver update requires a PC restart and it isn’t prompting all users to do so.
