Ever since two days ago... my comp has randomly stopping powering my keyboard and MS Intellimouse Explorer. I've been using the comp with the same keyboard and mouse for about over a year now. I start using my comp for 10 minutes, and everything's fine. Then eventually the red LED on my mouse flickers on and off, but the keyboard still works. Then a minute later after my mouse completely goes out, my keyboard goes out too. Any ideas on what could go wrong? I haven't opened my Mac in a long time, and I haven't installed any apps or updates in a long time except the recent iCal upgrade, but that's it.
