Hi,
I am using the system as listed below:
CPU/APU: AMD Ryzen 5 2400G
Mobo: ASRock B450M Pro4
Memory: 2 x 4GB Tforce Vulcan 3000MHz CAS 16
Storage: 500GB Samsung 970 Evo

I was using the system for two days, until I felt that I need to make changes in the BIOS.
So, I went to the BIOS, Changed the GFX Core Voltage from AUTO to 1.550V (which is Max) and GFX Frequency from AUTO to 2500Mhz (which is listed as Max).
Saved the changes and from there until now, neither Windows is loading nor I am able to enter the BIOS despite the F2 or DEL keystrokes.

Help needed.

The board cannot handle the changes. Turn the power supply off, manually clear the cmos settings by jumping the pins, turn the PS back on and try to start.....What happens?
