Please help, my computer is not working.

Alright so I upgraded my computer from windows Vista to windows 7 like 3 months ago so it's not too much or not too little. I had a little trouble with the installation but in the end everything is working fine with my upgrade (I'm not sure if this is relevant to my problem). SO recently my computer has been shutting down on me, it has happened like five times. As I tried to fix the problem and use start up repair it said the problem could not be fixed so I clicked on "Show more details" or whatever and it showed me Some "Signature" with numbers next to them and on signature 6 it said something like "osversionmismatch". I tried everything ! going back in time with system recovery point and also try to log in to safe mode but I cant... it either stays at the screen where is says "Windows is starting" with the logo on top or it gets past that and shows a black screen with a cursor on it. You can move the cursor around (But what good does that do on a black screen?)

I would really appreciate it if you guys could help me with my computer I really need it!


Update:
I took pictures of my sad computer

Let me know if you did an upgrad or clean install (had to reinstalll programs). If up grade, just bite the bullet and do a clean install.

Can you get in with safe mode?

You can make the DVD from any computer.

Once you get to the reapir console, it will depend on the option chosen to see if your filles are lost, but probably not
