i found some older MBO P5KPL-AM, and it hangs during post. when i turn it on, it hangs on this screen
if i press tab it shows posting screen, but then nothing happens
and if i press for example alt+f2 it says "asus ez flash will be..." and nothing.
3 different CPUs same thing
5 or 10 RAM sticks nothing
different PSU nothing
disconnecting everything, front USB, audio, HDD, DVD nothing
clearing CMOS, removing battery, nothing
removing GPU using onboard only, same thing
im testing MBO using pci tester, and it hangs on 3C on LED.
bios is amibios, and checking LED info online "memory test of lower 1mb ok"
im out of ideas except MBO is caput :/
