Hi,
I have brought new system 3 days ago and assembled it my self. It started properly but after 2/3 hours its stoped working and showing no display.

Configruration
Ryzen 9 3900x
MSI x570 a pro
Gskill 16x2 ram 3200mhz
NZXT krakken x62
Intel M.2 500gb ssd
Corsair vs650 watt psu
Old gpu amd radeon 7850

I have tested my GPU in other system, 750 watt PSU from my friend, replacement motherboard b450 gaming plus max. Still now able to start my pc.
Please help me out if anybody faced these kind of issue.

Thank you
Sourabh

Try using one stick of ram at a time and turning on your pc. Faulty ram or even one faulty ram stick out of all the others can cause the pc to power on, but you will get no display at all. You may even have to try different ram slots. Also make sure your ATX power supply connector is in correctly if not this could also be the cause of no display or power to usb devices.

I have checked with single ram stick also and ATX power cable i reconnect many time. Does not seem to this issue.
