Unable to find driver for this platform

So I just went to turn on my macbook and it wouldn't start all the way.
It stays on the screen with the apple until a message pops up telling me I need to restart my computer.
There is a message in the top left corner of the screen that says:

Unable to find driver for this platform: "ACPI"
Debugger called: <panic>
and then there are a bunch of letters and numbers.

I restarted several times but still can't get passed the apple screen without the message popping up.
The last thing I did before I turned my computer off (other than check my e-mail) is install all the updates.

Please help!

Also, I'm not too sure what all my mac info is since I usually find that out using the computer, but it's a macbook that I purchased last Jan ('07).

You need to do the backups before you do the installation. You can't do it from the installer disc unless you clone the entire drive to the external drive. If you wish to do that then see the following:

How to Clone Using Restore Option of Disk Utility

1. Open Disk Utility. Select Disk Utility from the installer's Utilities menu.
2. Select the backup or destination volume from the left side list.
3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
4. Click on the Restore tab in the DU main window.
5. Select the backup or destination volume from the left side list and drag it to the Destination entry field.
6. Select the startup or source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.

Well my external won't show up on the left side so I guess I won't be able to do it. If I continue without installing the bundled software will I be able to install those later?

You don't need to install the bundled software. If you select the option to preserve users and network preferences all your applications and user folder will be retained in the newly installed system. Please read the linked documents before proceeding so you understand what's going on and what your options are.
