My keyboard is wired and plugged directly into my Intel iMac running OSX 10.5.8. I do not have the Leopard disks, but I do have the Tiger disks. I was trying to boot in single-user mode so that I could run AppleJack to try to fix another issue I'm having--I get the light blue startup screen flashed at me several times daily for the past week or so. When the blue screen flashes, it totally freezes my computer (obviously) and lasts from 1-10 seconds. I can't find anything that is triggering it. I haven't installed anything new that I'm aware of, and it happens whether the computer has previously been slept or not.
Also, for anyone who is nice enough to answer, please explain everything--I'm not an expert user.
