Turned off PC to go out of town, needed to check something about 10 minutes later so I turn it back on and now it just boots to black screen.

Help needed, I've tried to reboot multiple times, moved monitors off of GPU to motherboard, still nothing. Yellow, Orange and Red lights on mother board.

What can I do?

The EZ Debug LEDs, surely not three of four stay on? They will all cycle through on every boot, that's normal, it's only about which LEDs stay on. On MSI AM5, we have several cases each week (almost a couple a day, it seems) where people get the CPU+DRAM LEDs staying lit, for no apparent reason. Check your LEDs again, you might be one of those people.

Don't bother looking at the screen or trying different outputs. With any of the first three LEDs staying on (CPU, DRAM or VGA LED), the problem needs to be solved first, there will be no picture until that happened. Only with the fourth LED, the BOOT LED, would there be a picture (of the BIOS).

Can you list all your hardware including CPU cooler and PSU?

Thank you, I'll get the information and take some pictures so you can see what I see.

The leds near the top right. It appears the top 2 are on, red then yellow.

can you do a CMOS Clear and see if it then Boots?

power it down turn off the PSU and Press the Clear CMOS button on the rear I/O panel and hold it for around 10-30 Seconds and that should do it and then turn the PSU Back on and try Power it up (it may take upto 7 mins for it to run RAM Training again so be Patient).

Another case of spontaneous CPU+DRAM LEDs for no good reason. We see a couple cases of this here every week, on MSI AM5 systems with otherwise usually pretty nice components. You didn't list your PSU model (the foundation of the entire system), but looking at your other hardware, shouldn't be a bad model.

There seems to be some kind of issue which only happens with MSI AM5 (not AM4, not Intel), and it seems to be something with the board, maybe with the contact between the CPU and the board. I have not found a good solution for it yet. Nobody really knows why this happens, but MSI have to do something about this, it's not normal.

Try with just one RAM stick in slot A2. If that doesn't help, try without any RAM (it should only show the DRAM LED then). If you still get the CPU+DRAM LEDs, then basically the RAM, SSD and GPU are pretty much ruled out. You can try without all that, and even with a different PSU. Clear CMOS too, of course. But often times people end up finding that none of this helps, and i would then open a ticket with MSI.
