Something happened(crashing and graphic issues) to my MacPro(3.1) and so I decided to reinstall the OS with the factory discs. When I try to boot off the discs I get the following error. Code: panic(cpu 0 caller 0x00431DA3): "Unable to find driver for this platform: \"ACPI\".\n"@/SourceCache/xnu/xnu-1228.4.20/iokit/Kernel/IOPlatformExpert.cpp:1407 Debugger called: <panic> Backtrace, Format - Frame : Return Address (4 potential args on stack) ...

It seems like the recovery dvd should be able have the driver for this system shouldn't it? Any ideas?
