I have a windows 7 Laptop a compaq presario I was streaming a video to my tv when my computer restarted. After that restart my laptop will not load windows. I can access my bios but when it tries to boot i just get a black screen with a flashing cursor. it does not tell me that windows is loading just as soon as i pass the manufacturer logo screen in goes blank. if anyone has any ideas about what might be wrong your input would be appreciated.
