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.
