So I followed the guide here and no luck.
Pc turns on and immediately off.
Specs:
I9 9900
Z390 tuf gaming
Corsair 2x8 3600
Gigabyte G750H
Aorus 2070
Samsung 970 evo plus
PC worked regularly for the past 8months.
Started failing this last Thursday, without hardware/software change.

Tried replacing PSU, SSD, RAM.
Reseated CPU Cooler.
Reseated Cmos.

Same result.
I'm out of ideas.
 
Breadboarding then.

Step #23
Well
I changed motherboard and now it turns on for about 20seconds and off and on again. Like it's really trying.
Anyways the cpu light is on. Constant red.
What's the verdict?
Could the i9 9900 die all of a sudden?
 
Please help?
cpu's are unlikely to die

have you breadboarded the sytem as suggested?

Yes
Now it's not responding at all.
The rgb lights of the motherboard is on, but it wouldn't turn on at all.

Update
So I took the CPU and motherboard to a PC lab.
It turns out the Motherboard is broken. Thank god the CPU is all good.
I'll send the motherboard for repair as its still on warranty.
Thanks all for the help!
