I have been having trouble with my desktop computer. Not sure when it started, but have re- booted and it would work for a day or two and back to the same issue. I says my DNS server is trying to access something that does not exist and to contact the network administrator, not connected to internet. Not sure what that means at all. I have a lap top computer which I am using now so this one is connected. So please anyone that can help I would appreciate it. Please explain in easy terms, don't know all the technology terms. Thank you
