AIDA64 Stability test failed. Fluctuating fraphic of GPU Power draw (MSI B450M Gaming Plus + Ryzen 3 1200 + Inno3D GTX 750)

[G3k0S]

Hi!

My PC:

CPU - Ryzen 3 1200
MB - MSI B450M Gaming Plus
Video - Inno3D GTX 750 2Gb - 4 years
PSU - Chieftec CHP - 500A - 8+ years
MEM - Kingston HyperX KHX2666C16/8G 2 bars by 8Gb.
HDD - WDC WD1002FAEX-00Z3A0 (931 GB).
SYS - Microsoft Windows 10 Pro 1809 Build 17763.379

Bios last update. Default settings.

Problems:

Sometimes Kernel-Power (41) mostly in games and tests Aida64.

Tests that I conducted (prime95(1 hour), OCCT(~40min), Memtest86(in bios (1 hour)), TestMem5), all is ok.  Sometimes the sound hangs. As if the whole system hangs for ~0.2-0.4sec.

The fluctuation in GPU utilization and GPU power draw is normal.  It's due to the way AIDA64 GPU stressing works: it issues an OpenCL kernel to the GPU (or GPUs) to put the workload on it.  The OpenCL subsystem however needs a bit of time to issue the kernels and then retire them as they're finished, and that's when the GPU can have a bit of rest.

Can anyone tell me what this is. Is it the CPU or Memory Modules
