Nothing obvious in your logs other than you have some obsolete Java versions which should be removed.

Java has been very vulnerable to infection so unless you absolutely need it you should not reinstall it.
If you feel you must have Java:
Get the latest Java at:
Save it to your PC then close all browsers and install it. Do not let it install the yahoo toolbar or other foistware.
(If you also want the 64 bit version then use the 64 bit version of IE to get it.)
You may need Java for NVidia's autodetect but make sure you have the latest.
Also visit intel and see if they have any new drivers for you:
High values of Interrupts in Process Explorer usually indicates a driver problem but yours is very low however it still sounds like a DPC Latency problem.
Try the DPC Latency Checker
It has a problem with Win 10 (a constant 1000 microsecond bias so it reads higher than it should) but I've heard that it still works otherwise. See if you see any big red spikes. Try bringing up one of your games.
I just worked another of these and he found some relief by searching for
msconfig
Hit Enter.
Then Go to Services tab and click on the box to hide Microsoft Services then uncheck
everything that remains. Go to Startup tab and uncheck everything. OK and
reboot. He claimed it didn't help but when he went back and reenabled everything it fixed his slowness.
Also keep process explorer running. If it starts stuttering try and get a log. That might show us a memory leak.
Another program to keep running is speedfan:
Download, save and Install it (Win 7+ or Vista right click and Run As Admin.) then run it (Win 7+ or Vista right click and Run As Admin.).
It will tell you your temps in real time tho the default is to show the hard drive temp in the systray. You can change it: Hit Configure then click on the highest temp and check Show in tray
This way we can rule out something getting hot under load. (Your temps when it is doing nothing are very low but I suppose there could be some problem under load perhaps the thermal paste wasn't put on properly)
Let's also look at your event logs:
(best to run this after experiencing stuttering)
1. Please download the Event Viewer Tool by Vino Rosso
and save it to your Desktop:
2. Right-click VEW.exe and Run AS Administrator
3. Under 'Select log to query', select:
* System
4. Under 'Select type to list', select:
* Error
* Warning
Then use the 'Number of events' as follows:
1. Click the radio button for 'Number of events'
Type 20 in the 1 to 20 box
Then click the Run button.
Notepad will open with the output log.
Please post the Output log in your next reply then repeat but select Application. (Each time you run VEW it overwrites the log so copy the first one to a Reply or rename it before running it a second time.)
