Hava a z690 maximus hero 12900k , 4 sticks of corsair 6000mhz ram , 4090 1500ax psu .
Well system just won't boot to bios even no display , would get stuck at q code for USB keyboard and mouse or 98 .
Removed.the.gpu but I would notice the power led would start to flash this happened 1st time when I turned on the psu even .
I thought maybe it's a ram error so I removed all the sticks except 1 .
Turned off and on the psu and light would become stable but if I would turn the psu off it would start to blink again.
Anyway did not get any post even when diredtly.connexted to the mother board hdmi .
Tried the bios flash back to latest bios pressed the flash button light tuned on and it flashed and after a while of blinking light turned off
But still no boot to bios .
And after all this now my 1500ax would turn on self test shows a red light , don't know what's going on here was working fine 10.min ago.
Tried removing the cpu re inserting same with ram .
Can any one help a very costly build
