Macbook Pro a1150 TROUBLESHOOT ME. whats the problem with mac?

[brandan003]

i bought this macbook pro a1150. it had a copy of snow leopard in it. but when i power laptop on it shows folder with exclamation point on it, its a grey screen, then the apple sign, then it lets me "install mac os" it asks to select the disk i want to install. no option for disk shows though.. i believe i have a bad hard drive. i have bought one already. will i be able to install the snow leopard dvd? do i need a serial number to activate it?

Did you check if the hard drive is placed in properly? Could be that it failed.

placed in properly? well i have already took the hardrive out and it looked like it was in there perfectly....

Run the Apple Hardware Test found on the Application Install DVD to see if the hard drive is still good.

this is my first time very using a mac and im starting with a broken one... so im not really sure if the snow leopard is the install dvd, but im pretty sure it is. but i would have no idea on finding the test, i just assumed the hardrive was messed up because the folder with exclamation point and no disk drive could be found. good thinking or no?

The brief folder and question mark mean the internal drive does not have an OS installed. It does not mean the internal drive has failed.

1. Boot to the install disc and choose English.
2. Go to the Utilities menu at the top of the screen and open Disk Utility.
3. I assume you'll see your internal drive listed in the left column. Click on it.
4. Choose the "Erase" tab.
5. Give your drive a nice name like "Macintosh HD."
6. Click the "Erase…" button.
7. Wait.
8. Once it's done, go to the Disk Utility menu in the upper left and choose "Quit Disk Utility"
9. Attempt to install Mac OS X.

Let us know how it goes!
