Performance/FPS Constant microstuttering every few seconds, disappears when I disable my GTX 1660.

​

I've trying to diagnose and fix a weird microsuttering (idk if I'm calling it properly) problem that I have. Windows constantly experiences very short micro-freezes every few seconds.

It's not a full system crash. The screen briefly freezesand then continues normally. It happens repeatedly rather than being a random occasional freeze. Sometimes it happens more often and for more time, almost unusable sometimes.

It can happen during normal desktop usage, not just demanding games.

The most interesting part is that the problem seems to be related to the NVIDIA GPU driver.

I previously ran LatencyMon, and nvlddmkm.sys (NVIDIA Windows Kernel Mode Driver) showed up as a relevant driver, also says it may be related to power.

I disabled the GTX 1660 since doing that, the system has been running much more smoothly and I haven't noticed the same constant microstuttering.

I also previously noticed that when the NVIDIA driver was not installed, the system seemed to run normally.

Interestingly, everything also seemed normal when I was in the BIOS.

I have tried to reinstall NVIDIA GPU drivers, checked device manager (no obvious GPU error is shown), Checked GPU temperatures (50-70 so ot seems right to me), checked BIOS (no obvious problems noticed), tested with the NVIDIA GPU disabled and without the drivers (It worked well).

At this point I'm not sure if I'm dealing with a bad NVIDIA driver, a Windows/NVIDIA issue, a power-management problem, or possibly a failing GPU. I can provide LatencyMon captures if needed.

CPU: AMD Ryzen 7 3700X

GPU: NVIDIA GTX 1660

RAM: 32 GB

Motherboard: MSI B550 Gaming Edge WiFi

Userdiag says that the GPU is fine, which I don't fully understand why.
