Hello!
I try to boot from a mainboard with following error beepcodes: 1-3-3-1 and sometimes (!) 1-3-4-1
I have two identical mainboards and tried different ram, also both dimm sockets (single and dual).
I tried 2 different cpus and still same errors. I tried to reset the BIOS by removing the battery over night (no power supply). Nothing changes. Fan of cpu is working.
Any suggestions how to fix this? Thank you.
