I attempted to jailbreak my 8G Ipod touch with Cyw00D and it screwed my Ipod up, i do belivie its stuck and DFU mode, now my computer says the USB will not reconize it, and also it will not respond to me its just a blank screen. Please help.

I suggest restarting the jailbreak steps. Just start from the beginning.

It's in DFU mode I assume, so you don't have to do that again but you can to be sure you did it right. I suggest doing it manually as you have more control but it sounds like you want to use a tool so just keep it in DFU and restart the process.
