    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.

    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) 
    Backtrace terminated-invalic frame pointer 0
    BSD process name corresponding to current thread: Unknown
    Mac OS version:
    Not yet set
    Kernel version:
    Darwin Kernel Version 9.2.1: Tue Feb 5 23:08:45 PST 2008; root:xnu-1228.4.20~1/RELEASE_I386
    I really don't know what to do from here... It seems like the recovery dvd should be able have the driver for this system shouldn't it?

    Any ideas?

    Usually it means bad or unsupported hardware.
    If you have stock GPU and you were experiencing graphics glitches and crashes before trying to reinstall OS, it's 99,99% your graphics card. Time to upgrade I guess.
