    My 2008 Mac Pro is suddenly causing me headaches.

    It´s worked perfectly before, but since yesterday it suddenly started booting every time, when I wake it up from sleep.

    What has broken?

    have you installed any new programs or hardware or has anyone but you used the machine lately it might be a power setting that has changed for some strange reason

    No. I haven´t done anything differently what I´ve done before and I haven´t installed any software or hardware. It just came from nowhere. :(

    Check the Console logs. There may be a hint there.

    Same problem, too it to the "apple bar" and got told, "It's old"

    Will call up apple on the phone tuesday and ask them to fix it, as it's actually really annoying now. I've turned off auto-sleep and the problem is bypassed.

    I'll update you with more info after tuesday.

    Same machine and I've never had that problem. I'm assuming you meant it (re)boots rather than simply waking from its slumber.

    My problem is much more sinister, however. I lose the ability to use my optical drive if my machine goes to sleep and wake. It's like it's not there at all and I need to reboot. I've traced it back to Snow/Leopard since this wasn't a problem with Tiger.

    Not saying this will fix your problems, but I have found that repairing permissions and running the maintenance scripts has fixed a lot of weird problems for me. Just a thought.

    You need to reset the SMC.

    I´ve done SMC and PRAM reset couple of times. I´ve repaired disk permissions, firmware is up to date, but nothing seems to work. :(

    I have used the sleep mode perfectly for 3 years, but now it just suddenly decided to stop working. :confused:

    Noooooooooooo!!! I don´t want start going through this "Windows BS" troubleshooting and researching the cause of this problem.

    (I wonder if my AppleCare is still valid...)

    That type of answer is totally unacceptably. You should speak to that persons boss or email Steve Jobs.

    I had the same problem with my 08 mac pro at the beginning. The issue seemed to be related to the video card (HD 2600XT). A firmware update for it (it was released a couple of months after the MP) fixed the problem in my case... You could try to find that update or install another GFX card if you are working with the 2600 at the moment.

    Ditto. But IMO it has been an EFI firmware issue. Installing Firmware Version MP31.006C.B05 fixed it for me.

    I did, and an apple repair person came to my house, replaced the motherboard and power supply fixing the problem.

    That's impossible. As the 2008 machines came with Leopard.
