heya,
the this is recently banged my laptop screen and threw my laptop. For this is i had a fight (thats something different) but apart from that the display has some problem. The thing is after this incident it worked for some 5 days but after that suddenly my screen had a problem.
1st image is the BIOS intro screen where it says lenovo.
2nd image is the windows loading screen.
3rd image is the windows disk check screen.(it had to as the windows was not shut down properly)
4th image is the windows login screen.
5th image is the windows default desktop screen image.
6th image is the windows log off screen.
my wild guess on it is that there might be some problem with the LCD cable. Sometime before windows started properly. Even now it is starting properly but as u see the screen is screwed up.
Want your opnion on this. Please help.

Your screen is likely damaged and needs to be repaired/replaced. The LCD cable may be loose, but then the symptoms would be the same all the time. If the laptop was thrown around, it is time to backup your data and get a new one I think, there could be other damage as well.
Your links post an extra 2-3 characters after the last /, they do not work direct...one has to delete those extra characters to view the screens.

I probably wont be much help as I am not that knowledgable with it comes to the more technically stuff with computers.
However, I got the dreaded blue screen about a month ago and after bringing it to best buy (I bought the full warranty), i was told I have one bad memory stick/RAM. It was replaced, problem solved.
So, consider that a possibility as well, although with it happening after that incident, it could be something else.
Format the Hard Disk and fresh install Windows 7. If it does not work then call a Hardware Expert.
i m nt able to see the pictures but as far as i cn tell is, first re-install the window cause log off is nt the prob because of screen ,its in software so first do it
and if your screen have lines of diff color in it that means u need to replace the lcd n believe me its really expensive
anyways try the first sol first
