Download Speed Slow On One Computer

My main computer has not been maintaining full internet speeds while my phone and tablet are?
I pay for 30/5 internet and my down lately has been super slow on my PC. hitting as low as 0.4Mbps up to 34Mbps... over the last few weeks its been hovering around the 4 to 17 range.
I monitored it closely one night for 4 hours and This Was The Result.
So after contacting my ISP and they came out we realized that this was my problem and not theirs. more specifically... it was my single PC getting low speeds. NOTHING ELSE.
My phone pulls 34Mbps consistently through the WiFi on the same network.
My laptop pulls 34Mbps Hooked up to the modem and via WiFi
My Tablet pulls 30Mbps through WiFi
My computer pulls crap from the router or hooked up to the modem.
I have installed the most up-to-date drivers for my NIC and the ones that came with the mobo disc and still crap.
I have uninstalled it and reinstalled the NIC and nothing
I just reinstalled windows yesterday and still nothing
i bought a wireless USB adapter and STILL pulling around 10Mbps right now.
and yes i tested this with ONLY the computer connected and no devices.
I have checked all my cables and ruled out any damaged cables (even though since the WiFi is working for everything else i know my problem is not in my router or modem.)
the problem exists on my computer alone regardless of connection type or path and is pulling crappy numbers from a network that is putting out great numbers... so the problem has to be internal on my computer....... but what???
OS:-----------Windows 7 Ultimate x64
MoBo: --------ASRock FM2A75 Pro4-M
Processor:----AMD A8-5600K APU Radeon HD 7560D
Graphics 2:---AMD Radeon HD 7850
Mem:----------Corsair Vengeance 16GB (2x8)
BIOS:---------American Microtrends vp2.10 3/14/2013
NIC:----------Realtek PCIe GBE Family Controller
Router:-------Linksys WRT160Nv3
Modem:--------ARRIS CM820

I updated to the latest Atheros 8152/8158 drivers v Download speed is fine, upload speed is not. Should be a 50 down/50 up Mb connection. Getting 47mb down which is great, getting.54 mb up which is horrible. Tried a different laptop on the same ethernet cable, speeds were great up and down. The problem only exists on one laptop.

I posted about this previously ~2-3 weeks ago here, and while the posted fix (flushing DNS) worked for some time, my internet (via wifi) has reverted back to speeds between 15-30mbps when it should be 180+mbps (other PCs, phones, tablets all posting this figure via and I have tried that same fix again, along with using countless other lines in the command prompt suggested in articles like this or this, and nothing has resolved the persisting issue.

Other things I have checked/tried include:

  • Plugging directly into the router (fast as expected)

  • Swapped out the wifi card for a new one (same speeds)

  • Tried a different PCI-E port (same speeds)

  • Disabled Windows 10 background updates (no effect)

What could I possibly be missing? I do not have too many devices connecting, as I have removed other devices on the network, there's no issue with the PSU or with grounding, it's not a driver issue (reinstalled drivers each time I tried a new card).
