Bit of an odd issue and I'm not quite sure what to try next. I've built and repaired hundreds of PCs and it could be me having a blonde moment in my old age.
B550M Mortar Wifi with latest 1B BIOS installed.
AMD 3900XT and 4 x 16Gb Corsair ram with NZXT Kraken AIO.
2 x m 2 nvme drives and a HDD. Boot drive is built in legacy mode
Everything running at stock speeds, no overclock applied, not even xmp profiles at this point to debug.
When I turn the PC on, initially EZ-debug shows red CPU led and PC does not POST. Press reset button without powering down and PC will boot normally.
I've swapped known good ram, swapped known good GPU, repasted AIO, reflashed BIOS, checked all MB driver's even though that shouldn't be a factor pre-post, reset CMOS, but problem persists.
This didn't happen until after an update to 1A BIOS.
Next thing I'll try is an air cooler to eliminate the AIO not starting as the cause, but....
What have I missed?
