Okay, so, I finally cracked down and took it to my local PC repair shop. The fellow working there plugged it in, booted it up, and everything went well. They said they would have a look at it and see what was wrong, even though they determined my RAM was no longer shooting up at a quick rate.
With that statement, I bid him farewell, and went on my way and wait to see what comes up. Between the time of drop off and pick up, I did research on some external hard drives to buy so that I could back up every little bit every week or so. I thought that after the PC was fixed, I'd ensure it to never happen again.
However, it wasn't necessarily fixed. In fact, I do believe it's in a worse condition. The man failed to back up the PC correctly, and when he tried to restore it, only some files (like a few in the %appdata%) survived, as well as every PC folder I had, and not a single .exe file (thank goodness I took a screenshot for some reference in case I accidentally buggered my background, allowing me to fix it,) made it through. Keeping a calm head, I paid him his money, left, and went to see if I could do anything to get it back.
Plugging it in, and booting it up resulted in a very familiar state...
IT WOULDN'T SHOW UP TO THE LOGIN SCREEN ONCE MORE. Frustrated, I thought "Well, then what the heck could be causing this havoc?", and decided it must lie in the cords. Putting that as the "only reasonable explanation," I raced down to buy a new PC display cord. And guess what was the result with that?
Success.
Coming to realization, I now knew I pretty much just paid some guy to wipe most of my files WITHOUT even the thought "Oh, jee wiz, it works just fine with my cables. Maybe I should tell him to go buy a new display cable first and then return to me if it persists," occurring to him. Outraged, I begin to tinker away, downloading .exe after .exe. But, sadly, with my country internet, I knew it was no use. I'd have to just wait for better bandwidth.
Okay, now after my excellent little story, I wanted to ask if there's any way to retrieve my lost files, or if I should just give up, and re-download EVERY little megabyte? I know cops can find some supposedly "deleted" files pretty well on hard drives, so, this gives me a sliver of hope.
Also, I looked at my system restore points, and not even any points from last year (my last restore point) showed up, so a System Restore is out of the question.
