Black Screen to Crashes After Matches. BS

I have been patient with Black Screen error, Been trying to play the best that i can, Now when Black screen was fixed, Now I have constant Disconnections after matches making it an unplayable experience for over a Month now,I have tryed Reinstalling, To cleaning out everything off my computer that has to do with crossfire to registry,stand alone files/Folders. Sending support tickets is not helping, at all.
