For the last 5 days upon initial morning bootup I receive weird artifacts on my screen and leopard does not fully bootup. After that, when I restart it - it's back to normal. Picture: http://img155.imageshack.us/img155/6473/picture2sl4.png Side Info: -I turn off my mac everynight, after doing a little research I've heard it isn't the best idea to prolong the life of my mac. (Mine would be off for 7hours before powered on again) -If I turn off/restart my mac in the middle of the day, I do not get this problem. SPECs: Mac Pro Gen1 2xQuadcores 3.0GHz 5gb of RAM NVIDIA GeForce 7300 GT HDD Bay1: 250gb HDD Bay2: 750gb Blackmagic Intensity Pro (PCIE Card) Any help would be appreciated. Thanks in advance for anyone who helps.
