Ipod screen is blank except for Apple symbol.

Hey,

I was just wondering if anyone else has experienced this problem with their iPod touch. It recently just decidd to conk out. By conk out I mean it's a black screen with the Apple symbol. I've tried turning it off and turning it on again. But that doesn't work. I even left it off for a couple days but that didn't help either. I had a couple of apps on it...do you think maybe it has a virus? Is there anything I can do myself to fix the problem?

Thanks in advance for any help!
