    It's been having trouble shutting down when it's gone unused. Then it won't turn on unless I turn the surge protector off and back on. (I thought it was tied to my backup drive being on, but now I just turn it on when I need it) Even then it doesn't start up automatically, I have to push it a few times.

    Just now when I held down the start up button it made a loud whooshing sound, started up, maintained the sound for awhile and then normal but I still hear it running louder than usual. I dread it may not start up again one of these times.

    What can I do! I am willing to try to fix it myself.

    Side issue, maybe unrelated but firefox is driving me crazy with proxy issues, aol mail issues, and just now I couldn't post in this forum it was "forbidden" when I hit submit. so I used Safari instead and found my post was actually posted. FYI

    Should I reset the CUDA PMU?
    How do I go about that?
