been lurking here for over a year and finally decided to register. and what a time to register, indeed. ok, here's the situation that i'm in... girlfriend's computer (power mac g5...older model...purchased around may of '04...has 4 RAM slots) gives out last night. she was using safari and internet explorer and the applications would quit on her. all of a sudden, the desktop would dissapear, then re-appear and then a weird kernal message on the desktop shows up and locks up her entire computer. i unfortunately don't know what the error message was exactly, but i rebooted the computer and it would not get past the grey start-up screen. i then rebooted again, inserted the mac os x install dvd and went into apple hardware test. it ran the hardware test and everything came out ok except for the ram. it gave me this message: post/0/2048 DIMM0/J11 doing some google searches told me that the RAM in one of the DIMM slots, DIMM0 to be exact, was no good. i opened up the g5, removed all the ram and trial and error'd installing the RAM until the apple hardware test showed me that there were no errors regarding the installed RAM. i am at that point now where i have ran the apple hardware test, both quick and through tests, and everything comes out fine. we're talking logic board, hard drive, memory, video card...the whole nine yards. i reboot the computer and now it still won't get past the grey screen. what do i do? how do i get past the damn screen?! applecare has long expired, so i don't feel like dropping $200 on a service call request. can someone PLEASE help me out here?! i'd really appreciate it!
