Let's cover the fact that Internet speeds and ping times have skyrocketed for many. Your PC looks to be in good shape as to the Speccy. I had to dig around to find anything to write about and they are a stretch.
If your stuttering is when you are on the Internet then you and so many others are complaining. I have no cure.
That aside.
1. Google Killer e2200 memory leak. I had that happen and it created a lot of stutters and more. Fix? On the web but I had to uninstall their drivers and such then get their latests.
2. Is there anyone that used Slimware, IOBit or other optimizers? These tend to break things. But no I have no fix. I defer to the optimizer makers.
3. Try other DNS entries. Test with DNSBENCH to find better ones. Google DNSBENCH if you never heard of this.
I have a Windows 10 64 Home hand built PC (Intel Core i7 4790K (not OC'd), 16 GB DDR3 RAM @ 1600 Mhz (XMP enabled), MSI GTX 1070 GAMING X, 250GB SSD, 500GB HDD & 1TB HDD, 650W EVGA Supernova G2 PSU) and it has run great for me for a long time until the past few months. Now i suffer from stuttering while gaming and streaming games.
Here is my Speccy: http://speccy.piriform.com/results/UnpmvO2KPacOsFFjotD2zav
Hopefully someone can help me out here, thanks in advance!
