Windows 7: Windows 7 crashes on startup. Can't restore, repair or repair install

Windows 7 crashes on startup. Can't restore, repair or repair install

All of a sudden, my computer crashes every time when starting up the computer. When it gets to the "Windows" screen with the small moving dots that form the windows logo, it crashes just as they start their animation.

I've tried using Startup Repair, as well as command line repair (possibly the same thing?), but they are telling me that they aren't finding anything wrong. Also reverting to a previous state results in an error and I can't do a system restore because I have no system restore points. I was able to backup all of my most important files, thanks to that excellent guide on here which tells you how to use the "load driver" window to do it. So, I'm confident that my hard-drive is still mostly functional, since searching through it went fine, with no corrupt files or anything noticed. At first I thought the problem was something other than my hard-drive/installation, so I put my hard-drive into another computer (which was working fine) and experienced the same problem.

I read about the "repair install" option and got really excited that this might fix my problem. However, I read that you can only do it while logged in (which, again, I cannot do) and this was confirmed when I tried to do it anyway. This sounds like the perfect option for me, but I can't get the computer to let me log in, whether in safe mode or not.

Does anyone have any other ideas about what I can do? I'd really like to avoid doing a fresh install of Windows 7, if at all possible. I'm sure there has to be some way to fix this, since I'm able to access all of my files on the hard-drive.

Thanks very much for any responses.

Have you tried running a sfc\ scannow from command prompt?

Yes, sorry - that was the command prompt thing I was talking about. I copied it from a guide. It said there were no errors (or something along those lines).

Can you boot in safe mode?.

Tap F8 during start up, and it should give you more options. Select boot in safe mode

Unfortunately that doesn't work either.

In that case. Try run a chkdsk /f/r in a command prompt.

Ok thanks, I'll give that a go now.

It's saying
"The type of file system is NTFS.
Cannot lock current drive.
Windows cannot run disk checking on this volume because it is write protected."

Not sure what that means :S

Edit: nevermind; typing "chkdsk c: /f /r /x" worked. I'll let you know how it goes.

It took a while to complete, but it finally completed and said that there were no bad sectors and basically made it sound like it was fine. I restarted to see if it did anything, but the same crash at the same point occurred. Are there any other things I can try? Thanks very much

It's a positive thing that it passed. That means there isnt any bad sectors on the HDD.
On which screen exactly does it freeze on ?.
