|Tried it, no result.|
Since I really need the computer to work again (the one I'm using is borrowed from my parents), I've tried System Restore, which couldn't work, so I resorted to one last thing: re-installing Windows. I thought it wouldn't be much harm since the only affected partition is C:, while others should be fine........
which turns out to be DEAD WRONG, since there's Comodo Time Machine in my PC which restored other protected data partitions (contains ALL of my music, games, vids, etc.) back to when it's installed, which is 8 months ago. I'm crying tears right now. Manly, heart-broken tears.
What I wanna say is, the problem is over, and steer clear from CTM since it's pretty much the cause for most of my problems (System Restore do just fine). Please learn from my lessons and DO BACKUP BEFORE YOU TRY. In another drive other than the one you're using.
*tears* I'm sorry for the unnecessary post, I'm so shocked & confused right now *tears*
