470-F random crashing problems

[FloridaPanthers]

Windows 10
Below is complete System Information

Up until yesterday, everything was fine. PC had been running great for a long time. No previous indications of any developing problem.

Then suddenly I heard a noise like a Brrrrrrrup (noise) and the PC froze.
I shut it down, took it outside and used compressed air to blow out any dust.

Now I can at least restart the system but occasionally and periodically, it freezes and I have to press the power button to shut it down.
I have backed up EVERYTHING just in case.

Now, I can get the system restarted and I can work normally for a while, then it freezes again.
I looked at the event logs and saw nothing that looked suspicious or indicated a potential problem that could cause this.
I looked over the SMART information and saw nothing abnormal.
All the fans seem to be working (Graphics card, CPU)
I checked the Ryzen 7 2700 running temp and the peak was 58C
Better post now before another freeze happens.....(Sure enough....it froze just after I saved and now I am back in...for now)

I'm suspecting the PSU but it's a decent one...nonetheless...it could be that.
I'll open up the PSU next and look for suspicious swollen Caps and check a few diodes and Mosfets.

My greatest fear here is a MoBo issue.

Any suggestions?
Thanks

Was hoping to get some opinions on this.

I've begun replacing components and I replaced the PSU earlier with a Thermaltake 600 Watt unit and so far so good.

If it does freeze again I plan to run a full diagnostic on my DRAM memory. If that passes, the next focal point would be the GPU, which I'm shaking in my boots over because I see the GPU I have is now priced over $500 :mad:

Nope.....

Froze up again after about 7 hours.

I would say that rules out the power supply.

I have replaced the GPU (GeForce GTX 1060 6GB) with a Nvidia Quadro 580FX just to see if the problem goes away.

Will know in a few days.

With the lack of high end video cards available today, I will have to find the issue with this one and repair it. That's going to tax my electronics skills considerably.

Removed the original GPU (GeForce GTX 1060) and installed a different GPU.

Did the exact same thing shortly after and ongoing.

I "think" I can now rule out the GPU and the PSU.
The SSD drive shows no errors or faults so I don't think it's the SSD.
That leaves basically the ROG Strix B470F mother board and the Ryzen 7 2700 CPU. (And the RAM)

Unless there's some odd way the OS could be causing this?

About to run Memtest on the RAM.

[FloridaPanthers]

SSD drive Health Status is good. No issues

[FloridaPanthers]

Ruled out RAM and CPU L1 cache memory banks

[FloridaPanthers]

I think I've ruled out everything but the ROG Strix Motherboard.

But the Q-LED lights indicate no problem.

This is Effed up when you have a problem like this....but nothing is wrong (or at least discoverable) and you aren't getting ANY help.
