Although this may be a hardware problem, such as your motherboard heading south, let's try removing all the other options first.
You mentioned running speed tests with both a phone and the problem desktop. Please borrow a friend or family member's laptop and test using both a wireless connection and a ethernet connection. That will give you a sure answer as to whether it's the desktop's problem. In addition, the secondary computer will give you the ability to download programs or drivers to fix your computer.
Next, do you get the same results if you run the speed tests with a different browser, such as Firefox?
You also didn't tell us whether you're downloading Torrents or sharing files. That gives us a clue as to what may be affecting your machine.
Next, because it may be malware causing the issue, click on the link and follow the instructions in the order they are given. You'll probably need the borrowed laptop to download the scanning tools.

And finally, just for grins, try running Chkdsk in "repair" mode to find any damaged files/free space and correct them. Start by opening a command prompt as an admin. Once there, type chkdsk /f /r /x, leaving the appropriate spaces between the letters as shown, then press the Enter key. You should see a note that it can't be run till a restart is done, type "Y" for yes, then press the Enter key again. Close the command prompt and restart the computer. Chkdsk will run upon restart and will take quite a while to finish.. Don't panic when the progress bar stays at 10% for a long time. It's fairly normal and the Chkdsk process may take a couple of hours.
When it's finished, it will boot to your normal startup/lock screen and you can login normally and then see if things are working correctly again.
Hope this helps and let know more.

Hey guys,
I have some issues with my internet connection.
Lately my desktop has been playing up, where to begin I'm not sure, basically it loads webpages fine, loads youtube fine etc, but whenever I try to download a file, the speeds will be under 100kbps. This issue only happens with my desktop, running speed tests from both my phone and my desktop shows these results -
Desktop: http://www.speedtest.net/result/6217487609
Samsung Galaxy S7: http://www.speedtest.net/result/a/2789261708
You can see the drastic difference in speeds here.
I can't even try updating the drivers on my machine as it only downloads at under 10kbps, and the download ends up failing or being interrupted anyway. I've tried both wireless and Ethernet on the desktop, both have the same results so I believe it is something to do with the system.
It is a HP ProDesk 400 G2. Running Windows 7 Premium 64bit.
Things I've tried include:

Doing a ip flush achieved no results.
I pinged both my router and my DNS (which is set to google's 8.8.8.
and both had 0% packet loss, my router was below 1ms and google was 93ms.
I then tried booting into safe mode and seeing if the issue continued there – which it did.
After this, I tried a system recovery, the furthest I could go, which was last month, and the issue continued happening. I'm right now at my wits end as to what is wrong, I can play on Xbox Live with no issues whatsoever, sites load instantly(ish) on my desktop, I am on a 100mbps FTTN plan through westnet (living in an area served by the Katanning hub in WA) and have no idea what to do next other than resorting to a full system wipe and reinstall which I really do not want to do as I lose all my files. I can't even download something like google drive to back my stuff up.
