Hi, I have a first generation mac pro that no longer works. When I boot up, I see the login in screen for a few seconds perfectly, but then the screen goes haywire--i.e., the screen shows tons of different colors in weird rectangular patterns. (I can't remember if it goes haywire only after I login...) I disconnected the computer a month ago, but it still has a lot of valuable files, so if it's merely a video card issue, I'll fix it. Does anyone have similar experience? I'm afraid to purchase a new video card and realize I wasted my money... =========== EDIT Ok, so I tested it again and cleaned the video card. It's not the video card. It's also not the hard drive because I can see my desktop for a short while before it all goes haywire. I guess this means it's the motherboard..?
