I started my macbook up and after the gray screen with the apple sign, there suddenly appeared a stop sign. Then I couldnt use my laptop as normal. Does anyone know why this is happening and what can be done to fix this problem? thanks so much!!

You should try the standard troubleshooting suggestions:
http://www.apple.com/support/mac101/ (see the "My Mac needs help" section)

In particular, be sure to do "Repair Disk" (different from "Repair Disk Permissions"!) in Disk Utility when booted from the Install CD/DVD. I.e. you restart from the Install CD/DVD, then run the version of Disk Utility that is available from one of the menus there (in 10.4.x, it's the Utilities menu), then go to the First Aid tab, select your boot drive, and click "Repair Disk" (NOT Repair Disk Permissions). If Repair Disk finds any errors at all, repeat the repair until no errors are found.
See this Apple doc:
