My iMac's screen just went black

[mrat93]

I was watching flash video and syncing my iPhone when suddenly, my iMac just went black. It started to beep very loud... BEEP BEEP BEEP... BEEP BEEP BEEP.

I held the power button and turned it back on. Everything seems to be fine.

So, anybody care to explain what just happened? I had the hard drive replaced by Apple a couple of months ago.

Here is an explanation of the beeps.

The beep code indicates a RAM problem. Since the RAM is easily accessible it might be beneficial to lay the iMac down, take it out and reseat it. Remember the Ram door screw is captive in the little cover.
