Question PC won't power up. PSU light goes on and off until I unplug the 24-pin to the mobo, then stays solid like normal. Already tried a different PSU...

I'm thinking the mobo is probably shot. Tried pulling out RAM one at a time, pulled gfx card, etc., no change. Any advice would be appreciated. The PC has worked fine for the last few months since I built it. I moved it to the living room to play on the tv and all of a sudden it wouldn't power up.

Specs:
Ryzen 5 5600X
Sapphire Pulse Radeon 5600 XT
G.Skill RipJaws V 2x8GB DDR4 3600 CL16-19-19-39
ASUS TUF Gaming B550M-PLUS
EVGA Super Nova 650 G5
Crucial MX500 2TB

Did you clear the cmos? With the PC unplugged remove the lithium battery from the Mobo then hold the power button for 30s x2s reseat battery then psu try to boot
 
Called ASUS support, they confirmed this mobo is done. Got an RMA but I'm not paying $40 to wait 3 weeks just to get the same lemon board back. Just ordered a new one, it'll be here tomorrow.
 
Are you receiving 0 power at all? Or are any case fans or any leds turning on? If you have power and things are starting just no display two things did you try with just the monitor again? And are you plugging the cable into the Mobo or GPU?
No fans, no leds, nothing. It's not a video problem, I'm not a noob.

Let me ask you this: I know conventional wisdom says I should clean slate start with a fresh win10 install and an ssd reformat, but what if I didn't? After all, I'm replacing the mobo with the same model and I'm not changing any other parts around. Shouldn't this theoretically work without all the fuss of reformat and whatnot? Or is there something I'm missing?

Same exact motherboard as long as nothing is wrong with the drive then just plug and play.

Personally I don't like Asus products I would of got a different brand.

Yeah I'm starting to see why. This is the second time in a couple months I've had faulty ASUS hardware. In the past I've never had issues though and this mobo still has great reviews so I'll give 'em one more shot here.

Lol that's actually kinda funny Asus is basically the only brand I trust some how I've only received maybe 3 doa and bad parts in general from them, it's seems as though all other brands I try to give a shot have issues somewhere either constant doas bad relays whatever the case I've never had a problem with Asus for the most part though

Not funny to me. About 8 years ago it was a good brand.
