this happened to me and I just fixed it. first plug in your touch to the computer. then hold sleep and home buttons until it turns on and off and then the second the logo appears release the sleep button but keep holding the home button. this will get you into restore mode!
Make sure that you hold Home and Sleep (Top), once it shuts off and turns back on RELEASE Sleep (Top) and continue to hold home until it goes into restore mode. You will get the message that shows you need to connect to iTunes.
or do it while pluqqed into computer with itunes on screen
all you have to do is press the top button until it shuts completely off. Then you have to press the home button then it should turn on. you can also put it face down and step on the back of it and a white screen should appear then plug it up to I tunes and it should work from there
