Question Motherboard powers on for split second without EZ Debug ?

[LunaKampling]

Hi all,

I replaced my motherboard about 2 weeks ago from a b450 tomahawk to a b550 gaming plus (the old one stopped working) and my system has ran mighty fine for those two weeks. Now today when I tried to power on my system it did not do so. After disconnecting and reconnecting power I have discovered that the motherboard LEDs power on for a fraction of a second, but the EZ Debug LEDs remain off.

12am, saturday right now. Desktop booted up without either sides of case in place after having power unplugged for 8 hours. Keeping it running overnight, though I’ll shut it down tomorrow evening and boot sunday afternoon. Will post next update on sunday whether it still runs then.
