If you don't have a current full backup, make a disk backup. No sense losing any data, particularly if your hardware is failing.
If you're on 10.6, boot the installer DVD, and see if that shows similar symptoms. If you're on 10.7, boot the recovery partition.
And reset the SMC.
Ensure you're patched to current; use Software Update to upgrade to the most recent software.
