I just bought a brand new custom built gaming computer and one of the first things I did on here was an internet speed test. My internet was stuck at about 80-90mbp/s which, while not really slow, is a lot less than I'm supposed to get. My old desktop as well my Dad's desktop get over 400mbp/s.

I googled the problem and used the command prompt to reset using these lines:
netsh winsock reset catalog
netsh int ipv4 reset reset.log
netsh int ipv6 reset reset.log

After running those lines in the command prompt I was able to get over 400mbp/s on my brand new desktop and I thought the problem was fixed. However, not even one day later my speeds again dropped to only 80-90mbp/s. The command lines worked to fix it again at that time, however the speeds slowed yet again today. THIS time those same command lines instead dropped my internet down to 13mbp/s and I cannot for the life of me get them back up to over 400mbp/s no matter how hard I try. Speed tests seem to be all over the place ranging from 15-90mbp/s even between successive tests.

Some things to know:
-I'm running Windows 10 and this is the computer I bought: http://www.bestbuy.com/site/cyberpowerpc-gamer-supreme-liquid-cooleddesktop-intel-core-i7-32gb-memory-nvidia-geforce-gtx-1080-3tb-hdd-480gb-ssd-white/5365805.p?skuId=5365805
-I am NOT on Wifi. My new desktop does NOT have any Wifi capability and is and can ONLY be connected via the ethernet cord. (Most things I googled had solutions changing Wifi settings.)
-I reset my router to no avail (considering other computers have no problem I didn't think that would help anyways)
-I don't have AMD Quick Stream or Network Genie installed or running, although if I have something similar running I have no idea how to find it. I looked through my processes and couldn't find anything that seemed like it would be a similar program but I can't be sure.
-I've restarted my computer several times.
-I checked for windows updates to make sure I'm up-to-date.
-My computer WAS able to get the 400+mbp/s speeds but they just kept dropping by the end of the day.
-No one else is using the internet and nothing is downloading/running in the background
-Reinstalled driver software for my network adapter
