LAN connection stops working 5-10 minutes while under load and causes computer to stutter/freeze

If the connection is under load ex. downloading files, it will suddenly stop working and disconnect. This then causes the computer to freeze every 5 seconds in 1 second intervals. I have tried updating the BIOS and LAN drivers but nothing has yet to work. The internet does work under wireless with no issue. The lights on the LAN port are a flashing green. This all began to happen shortly after reinstalling Windows 7. (not sure if related). Motherboard is DZ77GAL-70k intel. Anyone know any possible fixes to this issue?

  1. Let's do some basics:

    Did you install all Windows Updates? Including OPTIONAL except BING? Check them and repeat till ALL are installed.

    Download and run Slim Drivers, install all the latest updates but you don't need to reboot until you do the last update

    Download Malwarebytes do a full system scan (AV doesn't pick up alot of malware) - this resolved almost ALL other similiar posts to date as most had Malware the AV didn't pick up.

    Remove whatever AV your using and go to and download AVIRA, AVG, Comodo or Panda and do a full system scan - this repeatedly has resolved alot of people issue relying on MS Essentials.
    Repeat the AV/Malware scans till the system comes up clean.

    Download and run SPECCY, copy and paste the first tab to show your SPECS.

    Go through and provide a response on each point, don't SKIP IT because "I ALREADY DID IT" , just try doing it again as of THIS post so we know NOW what is happening as compared to BEFORE you posted.

    Antivirus your running? What is it and what happened when you did a FULL scan?

    try the stress test in safe mode with networking if you can. (Press the F8 key while the computer is booting after your motherboard logo dissapears)

    also try a chkdsk /f and sfc /scannow at the administrative command prompt. could be a system file that didn't copy correctly during that reinstall.

    I am surprised malwarebytes didn't find anything. I too can speak for the success of malwarebytes with this issue.
