Hi everyone, I have an old pc that start in a delay fore about 5 minutes. After plug it in, power button will do nothing for the next 5 minutes. I have tested the psu with another mono and it still work normally. I have replaced CMOS battery, it boot normally several times ang now the delay happened again. i also have flased bios to latest version, but it doesn't work. I saw from some unofficial source that replace some components in mobo should fix the issue. Is that correct? Is there anyway else?
