Vista - Location is not available, vista shuts down?

Okay so I come home and turn on my laptop, and it's taking a bit longer to start up. It comes to the login page for my user and i put in my password, then I get this error.

location is not available
c:\windows\system32\config\systemprofi… refers to a location that is
unavailable. it could be on a hard drive on this computer.or on a network.
check to make sure that the disk is properly inserted, or that you are
connected to the internet or your network and then try again. if it still
cannot be located the information might have been moved to a different
location.

and withing a couple seconds, it shuts down.
I have windows vista home.

I tried going to last good configuration. No help
I also tried system restore to an earlier point, then it tells me my driver is corrupted, so it doesn't allow me to restore.

HELP?

Repair Install For Vista

Hope this helps, if you need any other information just ask, good luck and post your results.

hey , thank you
but i cant even manage to get it to stay on
it automatically shuts down and restarts after it logs on :/

and in command prompt, i get this error when i try and scan
Windows Resource Protection could not start the repair service

Try this, go in to the Bios, (keep hitting delete on startup), set first boot device to CD/DVD, when it boots up, boot from CD/DVD, then do a start up repair.
Let us know how it goes, good luck.

Did you tried to start in safe mode already?

i restored it to an earlier point, and then this error came on when it logged on,

windows must now restart because the plug and play has terminated unexpectedly.

something like that

AND safe mode doesnt work , same deal, after logging on it just shuts down and restarts again

now is a little late to me,but tomorrow i'll post news to you,to try fixing your issue ok?
is a little weird your problem,when i said if you tried started up in safe mode,is because the sistem must start in safe mode without any problem at least pressing F2 or F8.

when i start safe mode, the same process happens
yes very weird indeed
