windows vista will not load pass the splash screen

I seem to have problem with windows vista .

So today I was using my computer and every thing froze and I had to shut down the computer and re-start it and it re-started pass the splash screen and gone all black stuck there :eek::eek:.So I re-started it again and doing some kind of disk check saying checking disk , deleting index entry misstmp , correcting error index ,recovering orphane dat and other stuff I don't understand.

It than re-started loaded again splash screen welcome to windows than goes all black again and I re-starts it and it doing the disk check all over again.

I than tried safe mode it loads takes long time froze at saying loading drivers crcdisk.sys

now I got into safe mode but don't know what to do.

I will see what others here say about the problem but sorta sounds like error or missing windows file .

It will not load pass the splash screen saying welcome to windows it just goes black and nothing works frozen.It seems when I can't get into windows and I re-start the computer it does this disk check thing .It did say 0 bad sectors. But it seems windows safe mode is only thing that will work but not sure what to do in safe mode or what to check in safe mode.
