Hello, I was at a mates place last night, and brought my computer over to play some games. We went out for a break, and when i came back, my headphones weren't working. And both the front and back ports aren't working. Thinking nothing of it, we went back to our plan for the night, to install an older model hd 7770 video card into my pc. The card turned out to have a busted fan, and my computer shorted out. I tried to return my computer on, but it wouldn't start, and the HD audio cable connected into my motherboard was VERY hot, unable to touch without burning. I immediately switched everything off, and let it cool down. I have recently been playing around with either HD audio and AC97, and i am still completely stumped. Everything in my pc is running fine, except for both the front and back ports. THe front and back usb's are fine. However, upon logging in today, Realtek HD audio manager is not on my pc anymore, so i am unsure of how to switch between the HD audio and AC97. I am completely stumped, and am slowly giving up. I need these ports for my gaming, and am accepting the fact that i will have to fork out some money for a usb headset. I really do appreciate any help, as i have no idea as to what to do.
