|It's a lot more likely you un-intentionally did something wrong that deleted the files than the computer deleted those files, or some malware you don't know about deleted the files, unless you have a ram problem, or a hard drive problem, or possibly a power supply problem.|
" I had no other choice I had to unplug it to turn off the power (since otherwise it'd sit like that until power was cut off to it).
You almost always have this choice even if nothing else works: hold the power button in until the computer shuts off!
You often have this choice:
Hold down Alt and Ctrl, press Del, let go of the keys. If Task Manager pops up, try closing whatever froze. If that doesn't help, try selecting Shut Down.
If the mouse cursor won't move or has disappeared, use the Tab key to toggle which selection is active, or type the underlined letter in the words you wanted to activate, use the up and down cursor keys in a list to change which one is highlighted, use Enter or somtimes space to select the selection.
Sometimes these work (they shut down the computer):
- Do this twice: Hold down Alt and Ctrl, press Del, let go of the keys.
- if you have a Reset button, try it!
You need to cure the problem that caused the freeze, and possibily the loss of your files.
How much free space do you have in the partition Windows is installed on, which usually C? If you don't have enough free space, all sorts of strange things can happen, including data loss.
See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
For a laptop, you must remove both its main battery and AC adapter before you do that.
Check your hard drive with the manufacturer's diagnostics.

Hard Drive Diagnostics Tools and Utilities
If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibilty, on another computer if you need to.
If those are fine, you might have a software problem
- run chksdk on all your hard drive letters, especially C
(Start - run - type: cmd (press Enter)
type: chkdsk C: (press Enter), etc.)
- run system file checker.
(If you have a generic system, insert your Windows CD in a drive. The CD must have at least SP2 updates on it - if it does, SP2 is printed on the CD. If you have a brand name system that still has it's original software on it, you probably don't need to do that.
Start - run - type: sfc (press Enter).
That takes up to a half hour to run.
You probably won't get any messages about whether it did anything. If it keeps asking for a CD or claims it can't read something on a CD, keep selecting Retry every time that happens and it will eventually finish. Reboot your computer when it's finished, and try your computer for a while to see if you still have a problem.
Possible and common, if this is a desktop computer...
Failing power supplies are common and can cause your symptoms.
E.g. burning a CD or especially a DVD places a extra load on your system that is more than most things do, and a faulty power supply may not be able to handle that - the burning program may freeze, or the computer may black screen and reboot while burning.
Check your PS.
See response 4 in this:
If you find nothing obvious wrong with the PS, try another power supply anyway - a used one or a borrowed one if you can get that to try first. My brother found that this was his problem when burning a CD made the computer reboot, only after trying another used PS - it seemed fine otherwise.
If you have a desktop computer...
Your CD or DVD burner drive may be faulty, especially if you have used it a lot.
Try another one if you can, or try your burner on another computer by burning a CD with it .
