After upgrading to 10.7.2, my iMac works fine for 40-50 minutes, then slows to a crawl.  Restart gets back to normal, then 40 minutes later need to restart again.  Thought about reinstalling Lion through Lion Recovery, but says my hard disk is locked?

After upgrading to 10.7.2, my iMac works fine for 40-50 minutes, then slows to a crawl.  Restart gets back to normal, then 40 minutes later need to restart again.  Thought about reinstalling Lion through Lion Recovery, but won't let me, says my hard disk is locked?  Any suggestions?

Launch the Terminal app in /Utilities/, run these two commands (copy & paste each one separately and hit the return key):
sudo chflags 0 /volumes/*
sudo chmod a+rx /volumes/*
at the Password: prompt, type in your admin password, carefully since nothing displays on the screen, and hit the return key. These should unlock your drives. You might have to restart.
