I have an MSI B350 Tomahawk Arctic mated to a Ryzen 5 3600 (with the updated BIOS, obvs) and I went to reboot my computer today, and it never came back on. It powers on, fans ramp up, and the "EZ Debug" CPU light comes on, turns off after a few seconds, and the fans ramp back down, but I'm getting no video signal, and my keyboard isn't receiving power (I can tell cause it has backlighting), which tells me it isn't POSTing. I've tried the following:
- reseat GPU
- Tried different GPU
- reseated memory, tried different sticks in different slots
- reseated CPU
- reset BIOS
- tried booting with no USB devices
- tried booting with no SATA devices
What I really need to know is whether my motherboard is dead, or whether the CPU is dead. I don't have any other Ryzen CPUs to test with. I literally have made no hardware or software changes, just hit Restart in Windows and now I get nothing.
