Whenever I start my MacBook Pro in anything but safe mode I get the blue screen.
Even the Leopard install disk and Disk Warrior 4.1 seem stuck at the blue screen??

I waited 40 minutes with Disk Warrior and then hard rebooted.

I am trying once more with Disk Warrior and will let it go for at least an hour...

Anyone know a reason why a CD/DVD boot should get stuck? The hard drive is only a few months old and SMART status was ok.

All this trouble started when my mac would not wake up and I had to hard reboot. I also saw some video issues at reboot with small rectangles of black and white all over the grey start up screen.

Thanks for reading,
Rob

macbook pro, Mac OS X (10.5.3), 100 GB 7,200 rpm drive, 2 GB RAM

Restart your computer with the original install disk in the drive. Hold down on the "d" key. This will startup the computer into the Apple Hardware Test. If you can't enter the Apple Hardware Test, you have some kind of hardware failure (with the logic board or maybe with the optical drive). You should call AppleCare Support to set-up a repair. If you can get the AHT to run, go through the extended tests and see if you get an error message. If you do, again, you should call AppleCare Support and get a repair scheduled. Let them know the exact error code you saw with the AHT. If you can run the AHT and no error appears, this does not completely rule-out a hardware failure, only a failure that the utility is looking for. Let us know what you find out.

    Thanks I will try that.

    BTW Alsoft called me back and said it might be a RAM issue. I waited almost 2 hours before hard rebooting out of Disk Warrior, held down the track pad button on reboot and it started okay. I am going to cross my fingers for the rest of the work day and try what you suggested tonight.

    Thanks,

    I just ran AHT from my original disk and it gave me a 4MEM/3/40000000 error the first time and 4MEM/2/40000000 error the next 4 times. I am going to check if everything is seated right and if so then off to the apple store tomorrow.

    Thanks again,

    Thanks for posting back! That would seem to indicate a problem with your RAM, the "mem"ory. If it's the original RAM from Apple, the folks at the Apple store should be able to help you get it replaced.

    Yep, I took out the RAM and switched the upper and lower RAM around, reseated them carefully, and the hardware error message went away!

    So far everything is running fine.

    Cheers and Thanks again,
    Rob

    p.s. I am the only Mac at work so if my box goes down I have nothing to turn to.

    I'm glad you got it up and running, but I'd still bring it in to the Apple store for a check. It shouldn't matter which slot either RAM module is plugged into...
