Moved Files One reason may be because files were moved and your computer needs to be restarted cause the computer was reading the files and they all of a sudden moved.

 Physical Faults One possible reason for this is that your hard disk is developing physical faults. Sometimes these faults may not be picked up by tools like ChkDsk however chkdsk is a good place to start I would advise using the /r option. There are other free tools around that can help you identify Hard disk Faults like "Drive Fitness Test". If any of these tests show that the hard disk does have faults it should be replaced as soon as possible. Software is available that will enable you to clone the faulty drive onto a new one.
put your computer in SAFE MODE.THEN DEFRAG.  
Check your hardware in device manager and see if there are any conflicts,(yellow ? marks), beside your display adapter, your monitor, and your sound drivers), sometimes a driver can become corrupt and you may need to update it. Also The defrag could have defraged a file in your registry that is no longer used, I recommend buying Registry Mechanic, this will fix any errors in your registry that can also cause freezing. One last thing, go into safe mode, and do a scan on your hard drive for errors, make sure before you do the scan make sure the box is checked for,"automaticaly fix errors". Then when that's all done, do a defrag in safe mode.
Like you I have had problems defragging, but I think that in my case it was something wrong with the defragger, as when i did it 2 weeks ago, then my computer crashed doing this, i restarted, 'Cannot Find Hard Drive', so then it went to a comp shop they fixed it, did disk defrag again, then computer restarted with the same problem, then it started to go through, 'Used Clusters' 'Unused Clusters' 'Bad Clusters' then here it takes forever to do then the computer frooze, so i turned it off, went and bought a new computer
Your problem is either a driver, harware or heat issue. Try updating chipset drivers with the original that came with your motherboard if it doesint work update with windows update to get the a signed driver, check to see if your hdd is running hot if you cant touch it get rid of it, update your bios if this occurs when you have just changed your hdd, disable the s.m.a.r.t function in bios if your hdd is older than 9 years old and lastly has i have seen enough before your video card is failing, change it.
