Ethernet doesn't have a valid IP configuration after updating

[LightinnNoir]

So I updated to Windows 10 yesterday and after a few quirks I got it to running as normal, or so I thought. I use an Ethernet cable to connect to the Internet but all I get when I diagnose is "Ethernet doesn't have a valid IP configuration". It used to work fine before updating by the way. This is what I've tried

• 
  Restarted the computer
  Turned off the computer, waited a few hours, then turned it on again
  Unchecked IPv6
  Re-installed the LAN driver
  Tried a different ethernet cable
  Tried to follow the tutorial on this website for Windows 8 for this issue but when I type ipconfig /release, it tells me that "an error occurred: an address has not yet been associated with the network endpoint"

Another funny thing I've noticed, when I enable the Ethernet connection, my computer skyrockets to exceedingly high temperatures (over 99C according to the monitor I have). When I disable it or disconnect it it goes back down to normal. Not exactly sure why this is happening.

Any help would be much appreciated, I know this type of question has been posted tons of times before but I've been spending my entire morning reading them and nothing has worked .

EDIT: played around with it some more. Looks like the temperature only rises when I check IPv6

Install the latest Windows 10-compatible drivers for your network adapter. Carrying over the drivers from Windows 8 often causes problems. As for your CPU temperature skyrocketing to 99C, that should have caused a thermal trip shutdown, so I am wondering if it's some unrelated malfunction.
