Oh OK then you do know how to do the usual troubleshooting stuff. (I forgot to mention the 'other PC' thing.)How about this. Unplug all shields/wires and put in just one led/resistor. The next time you manage to get it connected, immediately reprogram it with nothing but a Hello World Blinkie sketch. Then try a few reconnects. If that doesn't work -reliably- then it might indicate -either- a bad board, -or- some other more fundamental software incompatibility. Basically, keep stepping backward till you find something that works, then step forward till it fails again..
The problem is, ever since the second time its happened I haven't been able to get it to work again, but just now I just reburnt the bootloader onto the board using the arduino uno as an ISP, and its finally working perfectly 
yay yay, I'm not too sure if this will be like the first time it happened where randomly it stopped working again. But at least its something. Never been so happy to see a little LED blink 
lol.
---------------edit-------------
Its back to doing it again!! NOOOO =( =( =( =( =( =( =(
