I have no help on the screen flickering.

The increasing number of crashes indicates some other things may be 
wrong. The black screen is a kernel panic. A first step to dealing 
with this is to either startup from a different disc and then run 
diskutility to repair your disk. If you don't want to do it this way 
then reboot holding the command key and the s key. It will start up 
in single-user mode with a black screen. When it finishes you will be 
a a command prompt. Above it will be some instructions about running 
fsck. Type in fsck -y and press enter. This will run the same repairs 
that diskutility does. If when it finishes it says it found problems 
then run it again until there are no problems. type "reboot" to start 
up again. When it reboots go to the diskutility in utilities and 
start it run "repair permissions". These are starting places. If you 
still have kernel panics or a lot of crashes then more can be done.
