A couple things that might help determine what's up. What did you do that makes you think you fried it? (the action can possibly lead to the type of failure).<div><br></div><div>If it's no longer connecting to the PC, then it's likely got something damaged on board, or the bootloader is screwed...</div>
<div><br></div><div>You can always look up a tutorial on reflashing the bootloader, see if that works. If that won't work the board is likely toast (and I'm not sure how you would accidentally corrupt the bootloader lol)</div>
<div><br></div><div>I would begin troubleshooting the circuit, start with power and work your way down. You may have just fried the VR, in which case a new 7805 (or whatever it's using) would resolve the problem. Might have fried an individual discreet component, or the serial chip is toast, in which case you would need a replacement.</div>
<div><br></div><div>Then work your way down to the micro, and if it's still not working, chances are you need a new micro.</div><div><br></div><div>Just start with the easiest and trace your way back, eliminating possibilities. Divide and Conquer ;)</div>

How to check if I've fried an arduino?
<div><br></div><div>I have one I'm suspecting I fried but I don't really have a good way of verifying it. Any ideas? </div><div><br></div><div>I can't seem to load blink onto it.</div><div><br></div>
