GS3 Phone Black Screen

[Android Question]

I am rooted, I just installed Chaos Rom and then left the room while it installed. I came back and my phone was dead with a black screen and I cannot turn it on in download/regular/recovery mode. It also recognizes it is plugged into the computer but immediately says there was an error installing the driver. How can I get my phone to come back alive or at least show me what is going on so I can fix it?

Thanks!

Are you sure you installed a ROM for your carrier with the proper kernel?
If you installed from your SD card, pull it and confirm it was the right files

If it was the wrong files, I'm sorry, you will have to jtag your phone to get it to run again.

Good luck!
