Many Problems With a New Build

[equitem]

I recently built a new computer (a little over a week ago) and has worked fine until today, when I am getting many problems. First, I get no sound when I plus in my headphones to either jack. In addition, when I try to get to a website, I get a DNS error, but this does not happen with Google.com. I can google stuff, I just can't seem to reach other websites.
The internet connection is handling in.
Everything was working as of last night.

DNS error is possibly a problem with your ISP. You can try switching your DNS from them to the public one Google hosts. Instructions for Windows 7. https://developers.google.com/speed/public-dns/docs/using?hl=en

From what you wrote sounds like your motherboard is bad...if your computer was working fine a few days ago and then suddenly it doesnt work either you downloaded something bad or messed around with the computer settings which I dont think you did. on your computer. Update all your drivers and if you used windows update I would use system restore to restore the computer to a earlier date. If all fails reinstall windows. The motherboard should be under warranty.
