[SOLVED] No post beep and no screen on startup

[MouldyWood]

I bought all new parts (excluding the hard drive) and put them together. When I turned the computer on all of the fans were running and the lights on the case and GPU were lit but there was no post and no display on the monitor.

What I have tried:

• Removing the RAM
• Moving RAM the into different slots
• Removing the GPU

My components:

• PSU: BitFenix Whisper 450W
• MOBO: ASUS TUF Gaming B450M-plus
• CPU: AMD RYZEN 3rd gen
• GPU: ASUS GEFORCE GTX Phoenix
• CASE: Fractal-Design DefineC

Does the motherboard box have a Ryzen 3000 ready sticker?

If not, you may need a bios update.

I don't see a Ryzen 3000 ready sticker on the motherboard box and cannot access bios

You need to do one of the following:

1) Acquire an older CPU to update the BIOS.
With proof of purchase of your motherboard, AMD will loan you an older CPU to update BIOS. https://www.amd.com/en/support/kb/faq/pa-100
Or you can buy an older CPU to update BIOS. https://www.newegg.com/p/274-000M-0...EgGnddbbAFga3kIphFMaAtWEEALw_wcB&gclsrc=aw.ds
2) Return your motherboard and buy a Ryzen 3000 compatable one.
