DNS errors

Hi lately I've been having problems with my internet connection. I would often disconnect and I'd either get the error: "ERR_NAME_NOT_RESOLVED" or "DNS_PROBE_FINISHED_NO_INTERNET". I haven't lost the internet connection completely though, I'd often reconnect. I actually found a post by someone else saying that had a similar problem but I was afraid to try the solutions given to them since I was afraid it might not be the exact same problem and I'd make an even bigger mess. I'm running windows 8.1. I don't have these problems with any other computer in my house hold. I hope I'm not freaking out over this but the disconnections are frequent. I normally use Google Chrome's browser but I tried Internet explorer, and I get the same results.

I used to have malwarebytes on here but a friend told me it was bad(without offering any suggestions or advice on it) so I had it removed.

Hope you can help I'm kind of freaking out. I'll respond and do whatevers needed.
