You can try:
Perform a "hard reset" on the device by pressing down and holding the home button and the sleep/wake button for up to 30secs. until you see a black screen with the Apple logo, then release.
Then test to see if it solved the problem.
If that doesn't work, you'll likely have to perform a reset to factory setting (which deletes everything, make a backup): http://support.apple.com/kb/HT1414

1. Try a Restart by pressing the sleep/lock button until you see the slider. Slide to power off. Restart by pressing the sleep/lock button until you see the Apple logo.
2. Try a Reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider if, it comes up. Takes about 5-15 secs of button holding and you won't lose any data or settings.
3. Remove all apps from Recently Used list...
- From any Home Screen, double tap the home button to bring up the Recents List
- Tap and hold any icon in this list until they wiggle
- Press the red (-) to delete all apps from this list.
- Press the home button twice when done.
4. If still a problem restore with your backup.
5. If still a problem restore as new, i.e. without your backup. See how it runs with nothing synced to it.
6. If still a problem, it's likely a hardware issue.
