Toshiba laptop starts up but stays at "Starting Windows"

Hi there, so I have a Toshiba Inspiron laptop and its a 'problem child' sort of computer. I have had to baby it much in the past. It used to work great but a week after we bought it (used but in wonderful condition) it gave us the infamous black screen of death. My dad fixed it, but we have had to do everything but sing it to sleep at night. And now, just yesterday, after about a year of it kinda working, it fizzed out on me. At first it gave my the option of starting in safe mode or continuing normally, but then it would take me to the "Start Windows" with the little logo, and would stay like that for fifteen minutes or more. Then it went black completely. I tried the whole take the battery out, plug in the battery thing, but now instead of black I get the starting windows deal. And its not moving. Any help would be amazing, I need this laptop for school which starts next week!!!!
