Hi, I just installed a new HIS Radeon HD 6670 graphics card on my Gateway GM5474. The PC is completely factory except for 2GB of additional memory I added at the same time to give it 4GB total. The motherboard, CPU, and power supply are all what came standard.
After I installed it and booted the computer everything loaded fine, driver installed, I have a great picture, etc. However, I went to play a video on YouTube and it played about 2 seconds before cutting off and getting the YouTube error that it couldn't play the video. So I tried going to iTunes to play a movie trailer and upon opening iTunes it says it has detected an issue with my computers audio/video playback and may experience issues. Sure enough, I try to play a movie trailer and it doesn't even try to load. Final test was to try a DVD. My DVD player (VLC media player) said it could not play the DVD. I'm running Windows 8.1 64 bit by the way.
Does anyone know what the issue could be? Thanks!
