Ok, so... I just bought a new video card, ATI RADEON and I installed it fine and it works fine on my PC, BUT since the moment i restarted my computer after installing it i have not been able to get any sound, I have searched tons of websites for help on what to do and NOTHING has worked, i even had to do PC recovery at a point. Here are the things I've tried: - PC Recovery - Remove New card and plug monitor into old slot. (screen doesnt even turn on) - Reinstall sound driver - Someone please help me out with it. I dont want to spend any more money and this computer is my baby.
