LAN or Windows 10 Fault?

[Mekismo]

Hello all. Earlier in the year I purchased the following PC upgrade from overclockers:

*CP-539-IN Intel Core i7-4790K 4.00GHz (Devil's Canyon) Socket LGA1150
*MY-142-KS Kingston HyperX Beast 16GB (2x8GB) PC3-17100C11 2133MHz
*Dual Channel Kit (HX321C11T3K216)
*MB-502-GI Gigabyte Z97MX-Gaming 5 Intel Z97 (Socket 1150) DDR3 Micro ATX Motherboard
*CA-004-SF SuperFlower Golden Green HX 650W "80 Plus Gold" Power Supply - Black
*HD-026-KS Kingston HyperX 3K SSD 120GB 2.5" SATA 6Gbs Solid State Drive (SH103S3120G)

In the last few days I have upgraded my PC (and my laptop) to windows 10 and I have upgraded all the network drivers, since then I've been having internet issues. I am a virgin media customer and have a superhub. For some reason my superhub keeps locking up and I have to reboot it to get internet back. I called Virgin and the engineer replaced the superhub but suggested that the LAN port on my PC might be faulty. 3 hours after the engineer has left the new router has locked up again. I've disconnected the PC from the router now and I have found it seems to be working ok. Although time will tell.

My question is, could it be that Windows 10 is causing the problem or could I actually have a faulty LAN port on my motherboard (is the windows 10 upgrade a coincidence). I'm hoping it's not the latter as I really can't be doing with sending it back. Any suggestions?

Thanks in advance

buy a cheap pci network card and see if this fixes the issue and then disable the on board LAN.

If you'd like to rule something else out:

Disable XMP on the RAM, so it runs at the board's default memory frequency (1333/1600) and @ 1.5v DRAM, and try with just one stick and then the other. Can try different DIMM slots too.

It's rare but not unheard of for memory to cope well with everything except a few things. My RAM would do everything I asked, but would blue screen when closing certain programs. Lowered frequency a little and it stopped happening.
