System lag from keyboard input

Ever since upgrading to Windows 10, I have been receiving system lag randomly in/out of games. As far as I can tell, the issue stems from the keyboard or a driver, however I have replaced keyboards and cleaned all old drivers out. This issue only seems to begin when playing games (Arma 3, Heroes of the Storm, Diablo 3, GTA 5) and it is first noticeable by the Caps Lock key no longer toggling the light on/off on the keyboard itself. It will then further expand by full system lag anytime a button on the key is pressed (Dropping from 70-80 FPS down to 1-2 in game and in Windows and even causing audio stuttering from other programs like teamspeak)

Only way to temporary relieve the problem is to restart the computer. Unfortunately, I have been unable to duplicate the issue on purpose and it seems to randomly occur every 1-2 days. I have verified the BIOS (1604) and graphics drivers (361.75) are up to date. As far as I can think, the only thing I have not done is to do a full system reinstall, hoping I can avoid that since it is a pain to reinstall all games, etc.

Have you tried reverting to a revision of your graphics cards rivers prior to 361.75? It may also be the Logtitech Keyboard software as I've had similar issue with it though in part it was also the half baked drivers released by AMD for my A10-6800K machine to blame for the issue. Just to be on the safe side, try and re-install your Logitech software, the chipset drivers and lastly try view within task manager and see if any program/process is spiking with high CPU/memory usage which also means a memory leak. Consequently high HDD usage also would mean a similar incident as memory leak and the alternative is to perform a system restore(if the issue cropped up soon after a mandatory windows update), a repair install or a reinstall of Windows 10. Might also want to rule out the corruption in your bootable USB installer by recreating it. Speaking of re-install, what was your OS prior?

Just realized, off of your product support page you have a BIOS update with 2501 which is 6 revisions after 1604. Update it and see what happens.

Thanks for the response. I was previously running Windows 7 and I did a clean install when upgrading to 10.
For some reason I had 1604 written down, but I did verify I am on the 2501 version. Sorry about that.

This issue has been persisting for approximately 8-9 months now, so it has been occurring on previous versions of the GPU driver

This issue has persisted through different brands of keyboards, (already removed the software and drivers for those keyboards) but I have gone through and reinstalled the logitech software.

Never thought about download the CPU drivers, so I will definitely try that out. I have watched the resource consumption through the Task Manager as well as HWMonitor and while I do see the CPU maxing out when this issue occurs, there is no process in the Task Manager or through the Resource Monitor that accounts for the high usage.

Forgot to mention, I have run Prime95 For 8 hours with no failures (not the longest test but it should have shown something if it was CPU hardware) and MEMTEST with no errors.
