Okay, I'm going to try my best to explain the situation. I received an email from my ISP about a netBIOS vulnerability originating from my PC. Shortly after this email, I began having connectivity issues. After 30 minutes to 6 hours of the PC being turned on, it will "lose" internet connection. I say "lose" because according to my network adapter (ethernet), there are still bytes being sent and received. If I ping an IP address or website URL in my command prompt, I get a response. If I send packets to my router, I get a response. Yet, no programs or internet browsers seem to have an internet connection, except for google.com.
When I diagnose the Ethernet adapter using the windows troubleshooter, it says it can't get a DNS response. Following several "solutions" online, I switched to google DNS, no dice. I've done a number of refreshing and renewing in ipconfig, I've verified and repaired broken system files, I've done several full scale virus scans. Once the internet cuts, resetting the Ethernet adapter only restores connection for about 10 seconds. A restart is required. I tried resorting my PC to an earlier date, but was only met with an error no matter what date I chose. I tried turning off all firewalls to see if that solved it, no issue. Booting in safe mode with networking seemed to be stable, no internet loss, but virus scans were only met with errors.
Before I completely factory restore my PC, I wanted to come here to see if any of you had a potential solution. I've never had a problem on my PC this severe, and I've never had to go to a tech support forum, but I'm all out of ideas.
