You have quite a history here! I think you have a few issues here.
 
'''First I think your over heating your system:''' FanControl is not the best answer while it does work it also creates issues. People discovered they could use the same manufactures HD as their current HD [http://blog.macsales.com/2751-proprietary-cable-can-put-the-brakes-on-upgrading-late-09-imacs|OWC Blog on Late '09 systems]. Which I recommend first. I've heard a spare optical drive sensor could be used if you splice it in and mount it to the HD case (I've not tried this my self).
 
Have you been logging what your temperture and fans condition your monitoring software is reporting? I like '''Temperature Gauge''' but others will also work. You should note if the temp of the GPU is getting to high.
 
Have you cleaned the dust build up on the fans and the heat exchanger fins? As well as the logic board. You may want to start there.
 
'''Beeping:''' What is the beep code? Review these TN's [http://support.apple.com/kb/HT2341|PIntel-basedhttp://support.apple.com/kb/HT2341|Intel-based Mac Power On Self Test RAM error codes] & [http://support.apple.com/kb/HT5860|Mac computers: About startup tones]. While your EFI may need to be upgraded I would hold off on that for now until your system is stable. Please tell us what the code is.

'''As to having problems starting up:''' I would disconnect as much of the USB and/or FireWire external hardware and see how the system reacts. If you do find it improved things slowly add in the devices. You also may want to use powered USB hubs if you don't now.
