Hi, I bought 6420 XFR that tries to boot but shuts down after about 3 seconds, CPU gets warm, fan starts.
So far I have tested all rails wich are good, BIOS flashed with CH341, 3.3,5, main rail present. multiple ram sticks tested. Sometimes it might stay on for longer like 4-5 seconds but not always, theres no picture whatsoever. Also on some rare occasions the caps lock flashes 1 time by itself.
NOTE: I am using bench power supply not dell charger with ID pin and NO battery present, kinda doubtful this would cause this issue.
Any help is welcome. Thanks !
