Sadly, it sounds like your HD is in trouble! This could be just a be a messed up system file, badly fragmented disk or the disk could be failing.
 
Before starting make sure you have made a full backup of your apps and data!
 
Lets do this:
 
First you'll need to create (if you don't already have one) a bootable external drive. This could be a simple USB thumb drive (USB3 is best) or you could have a Thunderbolt HD or SSD unit. Once you have prepped the drive you will need to boot up under it.
 
Think of it this way you can't resole your shoe while you are still wearing it! That is why we need to boot up with the external drive.
 
OK, now you'll need to run Disk Utility from the external drives application folder. Run the repair permissions first (run it a few times to make sure all of the errors are fixed) then run repair the disk making sure you have selected the correct drive did it run though without any serious errors? Again you may want to run it though a second time. If it can't fix the error you need a new HD
 
Restart the system this time off of the internal drive is it better? If not you'll need to get a defragmentation application for the next step. I would recommend '''[http://www.prosofteng.com/products/drive_genius.php|Drive Genius]''' This is for the HD not the SSD drive! Sadly, you will need to buy the full package as the test version won't defrag the drive. Yes, there are a few freebie's out their that will do the job I've had too many bad experiences with them so I stick with a well supported app like this one. See how badly fragmented the drive is and let us know how it goes.
 
If the drive still is having problems we may need to look at other directions here. I would say better than 80% of the time this fixes things, 15% the drive has gone and the last 5% is the strange stuff.
 
Good Luck!
 
Lastly, [http://www.tunabellysoftware.com/tgpro/|Temperature Gauge] is also a very good fan & temp app I recommend if you need a good one.
