Hi,
My computer was fine just the other day, but i started it up today and now it wont boot up! I get an error message ‘Windows failed to start. A recent hardware or software change might be the cause.
File : CLASSPNP.SYS
Status : 0xc0000221
Info : windows failed to start because a required file is missing, or corrupt.
I put my vista setup disc in, i ran ALL the things it told me to (system restore, windows memory diagnostic, system repair, command prompt) but still they all fail.
I dont want to lose ANY files, because i have been doing lots of work lately on the pc and saved lots of important documents, is there a way i can reinstall vista without losing any of my important work?
