I just finished my new PC and I was at another person's house when I installed Chrome and other software. It worked fine then, I could go to websites and use software, but now I can Google stuff but not visit the website. It says something about my not finding a DNS thingy. (I am not on the computer with issue so I cant remember what it says exactly.) I trouble-shooted (if correct way to say that) my internet and it says the "Security or Firewall may be blocking connection." But I go on steam and it allows me to sign in and see friends, but not access the store, which is ran through their website. BTW I use one Ethernet cord for this computer and the one that doesn't work. this one and my living room one work, but the other doesn't. I hopped on that PC again to get the message displayed. It says "DNS Lookup Failed" and has the error code as "ERR_NAME_NOT_RESOLVED"
