I have also no idea what's going on. Just now, when I'm going to turn on my PC, I realized that it took about 20 seconds on the "Starting Windows" screen when startup. It just happened JUST NOW, it was ok yesterday. I tried to ran chkdsk, disabled many stupid toolbars, Skype, game clients etc. at Services and msconfig, defragged my SSD, update the firmware of the SSD, change my SSD from IDE to AHCI, still the same! I'm really confused. :S My SSD is Corsair Force GT 120GB.
