    I have in our recording studio Mac Pro. Last 2 - 3 months we have had problem, if we will start it, only light in start button will light, fans are working but nothing else, no picture in monitor and no start chime at all. When I push start button 5 seconds, it will shut down. Few seconds, I push start button again and all is normal, chime, light, fans and normal picture in monitor. Sometimes I must do this 3 - 5 times.

    And another problem, now very often Mac Pro can not find wireless mouse and keyboard, there is a sign: There is no bluetooth module in computer ( it is there). When I start again, all is OK but sometimes I must try many times.

    Can anyone help?

    Sounds like you have an actual technical fault developing in your MP. Have you tried resetting the SMC? (solves any firmware based startup/power management issues).

    How to reset the System Management Controller (SMC)

    Thank you, I tried but nothing new happens. This is very odd...

    I think it could be a faulty logic board. I would recommend contacting Apple Care Support.

    I opened my MacPro, took all memorys and videocard away and installed them again. Now all problems are away.
    Thank You:):)
