My mid 2010 Mac Pro will not turn back on when warm.


The front led light turns on as normal, but I get nothing on the screen. I have tested the screen on numerous other computers, and have even replaced the ati 5870 card with a brand new one.


I have even done a clean instal of the operating system.


The problem only persits if the machine is warm.  If the computer has been off for a period of time it will start up no problem.


Any ideas?

Mac Pro, Mac OS X (10.7.4)

    I can also log into the computer remotly when it happens and I can screen share.  It shows the display as connected.


    Here is the screen shot of the hardware monitor temps.  Waiting for the license key email so I can post all of the other values.


    Thanks for the help!
