I built a system 2 1/2 years ago. I used a GIGIBYTE B550M DSH3, RYZEN 5 3600, Antec 650W PSU and, GSKILL DDR4 Memory. System worked from the first time connecting and worked well for 2 1/2 years. Last week I started to get random lockups and needed to reboot the machine. The last time it locked up it would not start again. No fans, no display, no beeps, nothing. I am trying to figure out if it is the processor or the motherboard. Any ideas?
