Sorry to hear about this, you should try checking out the Support Article for this which can be found here.
I had this problem once (a long time ago now), and a GM suggested I move the entire installation to a new folder then try repairing it.
This actually worked, then also on his suggestion, I did a scandisk, which yep, there were a number of bad sectors. So I replaced the disk.
So, this problem can be caused by a dead or dying hard drive, or just by a few sectors that have gone bad on it.
