MSI Tomahawk not booting

Status
Not open for further replies.
Hello everybody,

I have a MSI B450 Tomahawk Max II with AMD Ryzen 5 3600, GTX 1650 Video. Yesterday I tried to start the system but no sound, no light no fans spinning. Checked PSU, 120V in ok, no 5V/12V out. Bought another PSU unit. Now I have lights and fans running but no display (HDMi input). Checked with different HDMi cable and monitor, same thing.
Tried with a known working graphic card (same model, from a second PC), no change. Tried with new DRAMs, no change. Then I noticed the red-lit CPU LED on MB. That, according to MB manual, shows missing/faulty CPU. Removed CPU, RAM, reset CMOS (JBAT shorted) then downloaded and installed (from formatted FAT32 flash drive) the latest BIOS from MSI site. No change. Tried a previous version of BIOS, no change, CPU red light is still on and no image. Just to make sure, CPU pins were checked under magnifier, they are all straight, as expected, since it was installed when system died.
Please help!
 
What is the PSU make and model?

Have you tried factory resetting the BIOS?

Ever since they stopped adding the speaker to the motherboards makes it harder to diagnose (to save money).

Reseat the RAM, GPU, DATA cables, Power cables, PSU to motherboard.
 
PSU is EVGA 700GD 700W. I did reset CMOS (BIOS to factory). I tried another set of identical DRAMs and another Video card. Power cables were reinserted since I have replaced the first PSU that was dead.
I did order another CPU. Waiting for it. The fact the "EZ Debug" light on the motherboard shows no-CPU made me think it is the culprit. I bit the bullet and ordered it.
