So I'm worried that I've killed my arduino and don't know if I need a whole new board or just a new chip. I accidentally left it on overnight with one of my projects, it was working great at the beginning but at some point the computer ran out of battery. My project uses both pnp and npn transistors so I have one line going from the emitters of the pnps to +5v and the emitters of the npn to gnd. They all have resistors on them, for the 3 pnps i think its .56 kohm and the npns have 2 kohm. And then of course I have the lines going from my digital pins to the bases of all the transistors to control them. When the computer died the board stayed on because it was drawing power through the +5v and gnd of my external power source (around 5v maybe a little higher and like 3.5 amps) this made the board not function quite right and then after not too long (I presume) it just stopped working. When I woke up I plugged in the computer and tried to upload the same sketch and it thought for a little bit and then gave me the below error. Please let me know what this will take to fix, I really hope I don't have to wait for shipping on a whole nother board.

And yes. I did make sure it was the right serial port and board.
