PC shut off abruptly, turns on but doesnt boot

PC was built 2-3 months ago.

Was running and working with no issues (max temps for CPU & GPU ~75C during gaming).

It froze for a second during gaming today and shut off.

When I'm trying to turn it on it turns on but I see no visual. monitor says that no signal is received from hdmi. although initially I see a notification on monitor that hdmi was connected.

RGB lights are working on gpu, cpu/psu fans are also working.

Build: Asrock 9070x Asrock B650I lightning AMD 7600 Corsair sf750

Tried:

• Resetting cmos
• Removing rams and replacing sockets.
• Removing GPU and running with integrated card
• Removing peripherals
• Replacing HDMI cabel

I think this board doesn't have debug leds or anything similar to check what's booting.

as I've read PSU might be working but not supplying enough power to properly turn on everything.

Any tips would be very helpful until I have time to take it somewhere and check with replacement parts
