Probable reasons are: 1. wrong password; 2. virus infection; 3. missing or corrupt Windows start-up files; 4. possible (though unlikely) hardware problem(s).
Possible workaround: a. try running Safe Mode; b. Reset/Delete your Password(s) (I'm sorry but I can not go any further as to how to do this. Best is Google for it); c. for virus scanning/hard disk scan/check-up/repair, you need to remove the HD from the PC where it is original installed and with the use of an external USB enclosure, connect it to a 2nd PC and perform the diagnostics from there. d. Re-seat/clean tips of your video and/or memory.
Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.
