Hi everyone. I just built a new rig 2 weeks ago. First I installed Win7 and I got random BSDs on pci.sys every 2-3 days.
So I installed Win10 and the same issue persisted but now it hard freezes completely instead of BSODing, so I'm assuming it's a hardware issue.
It only happens on light use (ie web browsing). While gaming it's stable. I tried disabling Global C-States in BIOS but the issue persisted.
I've never had an issue like this. I heard freezing with Ryzen was a power issue on Linux, not Windows.
I also heard the B350M Pro4 had freezing issues, could this also be the case with the B450 Pro4?
Could you help me spot the problem, or how to reproduce it? Here are the parts.


Newly bought:
CPU: AMD Ryzen 5 2600 (no OC)
Motherboard: ASRock B450 Pro4 (BIOS 3.20)
RAM: 2 x Ballistix Sport LT Red 8GB DDR4-3200 (BLS8G4D32AESEK) with XMP profile
GPU: EVGA GeForce GTX 1660 Ti XC
Chassis: NZXT H500
OS: Windows 10 Enterprise 64-bit 1909


From old build (~7 years old working flawlessly):
SSD/HDD: Crucial SSD MX100 128GB + 2 WD Blue + 1 WD Green
PSU: Antec HCG-620M 620W Bronze
