New build, PC start only after clearing CMOS, need help.

[navensavant]

It's 2 day old PC, with Ryzen 2200g on ASUS EX-320M Motherboard, paired with 8GB corsair RAM. I update the BIOS before installing windows 10 (tried installing win7 but did not work)

Now it just does not start when power button is pressed, but on clearing CMOS, and waiting for 15-20 mins, it boots up normally.

The chipset drives from ASUS dvd are all installed right after OS installation. The power plan is set to AMD Ryzen Optimized for windows.

Any help is appreciated.

All components
AMD Ryzen 2200g
ASUS EX-320M Gaming Motheboard
Corsair 8GB (Speed up to 2933MHz in BIOS)
1 SSD (120GB)
1 HDD (1TB)
1 DVD Drive
Corsair CX500M PSU

Corsair 8GB (Speed up to 2933MHz in BIOS)

Part number of the above?

Memory parameters also need to be set in BIOS. If left on [Auto] memory may be at too slow a speed for normal PC operation.

Your memory overclock is not stable, when you reset CMOS it goes back to the default speed letting it boot.

Thanks calvin7 and Zerk2012 for replying. Another symptom I noticed was PC shutting down itself when I tried to wake it up from sleep. I swapped PSU and to my surprise machine boots normally as expected, so it turned out to be CX500M PSU from Corsair which I hardly used fro 6-7 months.

I am able to keep memory at 2933 through BIOS, and it's stable now.
