By "the noise" I'm going to assume you mean the start up chime? If so as soon as you hear it press Command and R to start from your recovery partition. From there try running Disk Utility first to repair the hard drive, if that doesn't fix it start to your recovery partition again and re-install Lion.

Yes, the start up chime. The command and R isn't doing anything. How do I run disk utility?

Is Lion the original system for your Mac? Maybe I'm wrong about when to hold Command R, try restarting while holding the keys instead of waiting till you hear the chime.
