Hi, Im having an issue with my mac pro powering down my monitors. Up until a couple days ago the screensaver would turn on and 5 minutes later it would shut my monitors to sleep. Two days ago the monitors stopped being powered down. The only thing that has changed has I started using Handbreak over Visual Hub and I installed the Starcraft 2 beta. Could this be a PRAM problem? Any other issues I should look at? Thanks!
