Problem with Asterisk

SOURCE: My number eight will not work.

Still could be a bad keyboard. Try hooking up an external keyboard to the computer, and hitting eight. Do you get the same result? If so, then it could be software. If not, then your internal keyboard is most likely bad.

SOURCE: Hello, since yesterday my macbook pro is frozen,

Take the 2 RAM chips out and make sure they are compatible with your computer and make sure the RAM chips are not broke or defective. Re-insert new RAM chips and make sure they are firmly inserted in their bays. Also, install disc 1 of your 2 disc gray set and hold down C key to boot from disc. Then click on tab for install English. Then go to the top of the screen to utilities and click on disk utility. Now on the left side of screen select your hard drive and then at bottom middle of screen select repair disc. Then when that's done select repair hard drive. Now quit the disc and choose restart from hard drive. See if that don't help ya any. Also, could be bad boot sector in which you will have to save all your data and re-install the operating system. If that don't work, then look into getting a new hard drive and then re-install the operating system. Take your computer into the Apple store and have the Apple dorks look into it if your still under warranty, because you just dropped down some serious cash on this machine.
