My laptop wont got past the start screen

Hello,
i was looking at vids one day and my power died...i didnt think anything of it so i just let it be, well a couple days later it wouldnt start at all, it just goes to the blCK screen and says the options: safe mode, safe mode with networking, safe mode with command promt, last known good config (your most recent settings that worked), nad start windows normally...well if i choose one of these it goes to a BLUE error screen that goes by to fast to read, any help as to how i can at least get it to start it up and see what the problem is would be helpful...thankx alot
