Hi everyone, I just finished building my first computer today. I have a wifi adapter and it was working fine until i had the computer for updates now its not doing anything. I went to speedtest.net and i was getting .5 mb/s, compared to my laptop which gets 30 mb/s. I know its unrealistic buts it the best i could do. Its a tp-link wdn4800. And I'm using my tv for a display its a 50" sony bravia from like 3 years ago. I was getting full screen until i updated the driver for my video card (sapphire 7870xt). And now there is roughly a 2" black border along the pciture. It's not cut off its just missing screen real estate. And i'm also getting a crackly pop sound every 10 seconds. It's not super loud but its annoying. Its plugged into my video card.
