I have bought the parts for my gaming pc and there’s a suspicious red flashing led going on and off here’s my parts:
Ryzen 5 2400g
Msi b350 mortar
1x8 Vengence ram
Coolermaster masterbox lite 3.1
240gb western digital m.2 ssd

I have double checked if my connectors are connected and when I put my 24 pin power connector in it doesn’t do anything I tried the reset button and the power button on the wall and psu

When I pulled it out I noticed a red flashing led so I put it in lightly and it started flashing repeatedly every time it turns on every fan goes on.

If anyone has any helpful ideas please put them down in the comments

Check the manual of your board, perhaps those LED's indicate a certain device failing. If I had to guess, your board might've shipped out with a BIOS that wasn't updated, making compatibility with the new 2000-series processors from AMD an issue. If that is indeed the problem, then you can do one of the following:

Contact a brick and mortar store and see if they offer free BIOS updates.

See if one of your friends/someone you know has a 1000-series Ryzen chip that they'd let you borrow to update the BIOS

Contact AMD and register for their boot kit, which lets you loan a CPU out to boot your system.

Return the board and go for a B450 chipset one, which ensures compatibility out of the box.
