My iMac was working just fine a few days ago. When I got this computer it came with 1GB of ram and I very recently upgraded it to 2GB. I installed my programs on it (which need 2GB to be useful) and I then ran a software update. The software update was in progress for HOURS and wasn't making any progress at all. So I held the power button and shut it off. Next time I turned it on I didn't have the power chord all the way in, and the computer sounded like it had the fan running extremely high. So I thought silly of me, and restarted it again with the power chord fully in. It was all working just fine. I watched a few shows on the internet, and left the computer on until the next day. I come back and go to hit back in the browser and I got nothing but a spinning mouse wheel. About an hour and a half later with no progress, I shut it off. NOW THE COMPUTER DOESN'T SEE THE STARTUP DISK! 
It makes two beeps (one short and the next long). I tried to run DiskWarrior to rebuild the directory, but it does not see my computer's HD. I researched the two beeps and found they may mean incompatible ram.
So I had a way of checking the ram myself, I swapped it with 2GB of ram from my mac mini. My mac mini sees the iMac's ram, and the iMac has the mac mini's ram and still the same problem. I can't believe this. Haha sorry about the details but I thought I should explain anything that might have led up the problem. Does anybody know what's wrong?
