I was installing a game when the computer slowed down followed by a bluescreen. After restarting, it was slow right away and gave me bluescreen after just a few minutes. After Another restart I couldn't even enter Windows, it just loads forever. I thought "well, time to reformat" BUT the same thing happen here, it just loads forever on the preparing windows screen.
I then tried to put my SSD in a friends PC and boot from HIS SSD, but the same result occur, his windows cannot start. I remove my SSD and his windows starts normally again. Same thing if I put the windows cd in his PC and try to reformat my SSD, it freezes.
In short, no other hard drives or even CD readers work as long as my SSD is plugged in, thus I cannot reformat it in any way.
