Macbook keeps crashing and won't start up

[wilu23]

I've been trying to fix my macbook for couple days now.
I've erased the entire HDD and installed leopard OS on it.
I didn't want to install anything on it besides msn since the problem keeps popping up. So basically what happens is safari and msn keeps crashing everytime i start up my mac and try to use them.
If it doesn't crash, i get a "you need to restart your computer..." screen.
Now its worse... i get a message right when i turn on my computer:

panic (cpu0 caller 0x0042F4E3): "Unable to find driver for this platform: \"ACPI\". \n"@/SourceCache/xnu/xnu-1228/iokit/Kernel/IOPlatformExpert.cpp:1378

So i've tried the apple hardware test before i got this long message and results were ok.

macbook is running 2.1ghz core 2 duo, 120 HDD, 4GB ram.

I've tried switching the HDD and everytime i boot up, it'll give me a "you need to restart your computer..." screen.

I have an appointment at the genius bar on saturday but if i can fix this before saturday it would be great.

Any help is appreciated! Thanks!!!

im no expert, but it sounds like you might be experiencing some problems with the HDD and/or OS itself.

When you installed the version of Leopard again, did you verify/repair disc, and verify/repair after you installed the OS as well? Sometimes the HDD can act up a bit.

Also you say, you swapped out the HDD, did you screw up the internal workings, cos sometimes that can have adverse affect on things from an OS point of view.

Hope that helps
