Vista boot issue

#1
Alright, my pc suddenly crashed.

- now i cant log into vista, it gives me the option to start windows normally.
- or run the startup repair.
both give me the same outcome. a black screen with only my mouse showing.
i downloaded the iso file for the vista recovery, burned it to a disc, but i still cant boot from it, it is selected first in the bios. ive even gone into the bios and booted from it there. no luck. when it prompts me to press any key to boot from cd, i do. i get a microsoft loading bar. then a black screen.
