Go into system restore and restore your computer to a point before the 13.4 drivers.

Well I deleted the drivers and then it worked on the HDMI channel but I had to restart my computer so I restarted it but when it turned back on it didn't work again so I tried a different HDMI Cable for it to work and it didn't work as well so I tried to use my old monitor that has HDMI and it still doesn't get the signal from my PC so I am assuming it is my graphics cards HDMI Port that is broken but it doesn't explain (to me) that it worked b4 I restarted my computer.
