This machine has been letting me down a lot lately. First of all, the computer beeps about 20 something times early in the morning when I'm trying to sleep. I have not found ANYONE on the internet with that same issue. I've been through pages and pages of google and still no luck. Next thing, it randomly restarts whether if it's on Windows or OS X. Sometimes the computer gets really hot and goes "BEEP BEEP" at about a million decibels. I've also have had extremely slow Internet. It's slower than dial-up, even if the iMac is right next to the router. It's been two years, also, and the manufacturer warranty has expired and I'm not legible for apple care. Any help?
