My brother is building his first pc, he is miles away so I can be there and help him myself.
He has a ryzen 3700, radeon 5700xt in a Msi x570 a-pro
When powering it on fans spin and lights come on but nothing posts.
A Cpu error light come on on the motherboard.
He has currently tried a cmos restart, using a DP instead of a HDMI, tried with and without the gpu and using only one RAM slot.
If anyone can help to identify the problem that would be great.
Thanks in advance
