I had to reformat!!!

I've had to do that before. In a typical perfect storm comedy of errors, I lost my thesis, all 5 backups of it and the hard drive one day near the end of my Masters. I spent the next week piecing together parts of files I was able to salvage doing various "bit/byte editing methods". Then I had to rewrite all the missing gaps. Made me actually cry. But, it was a manly cry.

Hope it works out for you. Hope you find your computer faster now.

Good Luck
