I have an Inspiron 5100 which is about 2 or 3 years old. I turned off my computer one day and now it wont turn back on. It starts to load, gets to the screen where windows loads, and then a blue-screen error message pops up and disappears before I can read it. Then it starts over by booting up and doing what i previously said in a never ending cycle. Does anyone know how to fix this or what is wrong????
