I didn't unlink HD and CDrom, but I reset the bios and try with restart with HD or floppy, either way doesn't work. :-(( keyboard and monitor doesn't response. I asked a guy to try my cpu in his pc, it's good.
It's very very bad, my home computer doesn't wotk anymore. I may hurt matherboard, or power is bad. Anyway cdwriter is bad for sure, is there anyone know where to fix them? help please.
