[SOLVED] Motherboard not POSTing successfully after Windows update ?

[doomtrain44]

Hi All,

After my PC performed the latest Windows update, it did its' usual restart at the end but now it won't even POST successfully. Its' doing 1 long beep and 2 short beeps. I've tried reseating the memory/taking modules out/adding 1 stick in each slot but it still won't POST successfully. It's really strange because I didn't touch anything in the case, I only did a windows update.
Any clues?

Mobo: Asus prime x370-pro
CPU: ryzen7
Mem: 4 x GSkill TridentZ DDR4 8GB
gfx: msi 1080

After spending 4 hours into the wee hours of the morning, I managed to solve it.
Turns out I just needed to clear the RTC RAM jumper.
