- What does the motherboard manual say about the meaning of the red light?
- Better try it outside the case with the minimal hardware (PSU, motherboard, 1 stick of RAM, keyboard, monitor). What happens?

Thank you for your advice, I try to look at the manual and see. I also have a doubt because of APU ryzen 3 3200g that it might be a problem and needs a bios update for this motherboard though it has a sticker ryzen 3000 ready ? can't find the info if it's compatible just out of the box.

If a seller sells an out of date product.

Then they get a lot of returns. Call them up and ask them to fix it. Or just RMA and get a board ready to go.

As to the compatible, that would be the motherboard maker's site, the page for compatible CPUs which call out which BIOS to use.

Thank you for the advice. I checked and the red light is for ram. There are 4 slots for ram and only 2 are working so at least I know it's not ram problem, it should be somethimg with motherboard or it's slots. But I could at leadt enter the bios and install windows. Still dont know whats wrong and if its really a.mothrboard issue. I have to decide.quickly if return my motherboard or look for.solution. thank you

Heat sink

Red light means something wrong with the hardware. Please check the CPU for any bent pins on the socket. Make sure that the CPU heatsink is properly seated and also be sure that the heatsink fan is connected to the CPU Fan slot.
