New computer drops internet randomly/false negatives

I just built this computer a week or two ago. It's been working fine for the most part except that my network port seems to randomly disconnect on occasion. Sometimes it disconnects and I can't do anything except disable and re-enable it (fixes). Sometimes it says "no internet connectivity" but I am using internet applications without any issues.

This is by far the weirdest bug I have ever encountered with windows and drivers. I am using the Sabertooth x79 Motherboard along with the intel 82579v gigabit ethernet port on it. I have the most up to date drivers from intel's website. I'm not really sure what information you guys need to help me work through this problem. So please request anything you guys feel will help me. Kind of hard to test it out because it happens randomly and may not happen for a day or two.

Thanks

SFC /SCANNOW Command - System File Checker
Before doing anything could you give that a run, Afterwards if you could follow the steps in option 3 and upload the text log that may be helpful too.
I just want to make sure your windows installation is proper before we start troubleshooting this.

Hi. Thanks for the response. I really appreciate it. I have completed the sfc as requested and here is the cmd output:

Code:

Microsoft Windows [Version 6.1.7601]

C:\Windows\system32>sfc /scannow

Beginning system scan.  This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection did not find any integrity violations.

I also have attached sfcdetails.txt to the post. Thanks :)

Hi. I am not using any external firewalls, just the integrated windows firewall. I have never had any issues with this before. I am at my college with the dorm internet. The dorm internet actually assigns individual ips to each and every device as I am fairly sure the internet is connected to the backbone of the internet (100mb up and down). So we don't have individual routers per say.

I have a virtual machine that I have running but this issue was going on before I installed that, and it actually crashes as a result of the windows network disconnecting. So....not really sure the firewall or the VM is an issue. I honestly wonder if it's just a bad connection on the MB. But I want to further debug this with you. What is next?

I have not yet been able to test this computer on another network as it's at school with me and I don't have access to any other networks since it's a desktop. I have also used this internet before with my previous computers and never had these issues

Ok I will not actually be around my desktop this weekend, so when I come back on Sunday evening I am sure it will have broken at some point and I will give you the screenshot of the ipconfig /all. Will be back in 2 days. I really appreciate the help :)

Okay I am back and experience the issue when my computer was turned on this time. I have attached the screenshots. Thanks
