I have a Toshiba PSLV6U-00J001 laptop and i have had it for around a year. It just started freezing up for the past month (exept for in safe mode). It freezes everytime i turn it on around 1-2 mins. after i log-in to my user on the computer. the only way that i can shut it off after it freezes is to force shut it down by pulling out the battery. Please Help!!!
