Given so little to work with, I refer to http://reviews.cnet.com/5208-6121-0.html?forumID=45&threadID=35190&messageID=407618 so you can dig up more information.

Here's the ForumTip in case you missed it -> If you are asking for help to troubleshoot a computer-related problem, please be sure to include all the necessary information (ie: operating system, model number, hardware, software, etc) that will help others identify your problem for a speedy resolution.
