[QUOTE="Macosaurus, post: 1587016, member: 327316"] You're right, the problem may be something other than the graphics card; I was going on what the Apple folks told me. I figured right off the bat that if I could see anything on the screen it was odd that I was being told the video card was done. Here is what I know from the beginning: I was working in Photoshop when my screen suddenly went dark. The screen was still on but displaying solid black. After a few minutes of this black screen, I decided to power down by holding the power button on the Mac Pro. After 20 minutes or so, I powered back on... the computer started normally until, just when the desktop usually appears, the screen turned solid, bright orange. There were no icons visible. I then read about a number of people who had this same thing happen, and when they changed their graphics card, the problem was fixed. The problem is that most of the posts I read were written when the graphics cards that work in the 2008 Mac Pro were still widely available (i.e. 2009-2010). I'm not a computer technician, so this sounded like it was the problem to me, and this was also the opinion of the folks I've mentioned. When it occurred to me to run the startup disc diagnostics, I found it reassuring that I the display seemed to be working. The basic diagnostics found NO problems. The extended diagnostics then told me it was a HDD error. Again, as a non-technician, I became confused. I tried to boot from disc holding "c" and the computer shut down. I tried "option" and chose the disc and it stalled at the Apple screen. I tried to boot into windows but the screen stayed black. I zapped the PRAM... no change. As it stands, if I turn the computer on and let it boot it displays the grey Apple screen and then shuts down. Booting from the disc won't work (and I have tried putting my blank partitioned HD in the first slot). I have ordered Snow Leopard but suspect this won't boot either. I don't know what else I can tell you that might help. Maybe repairing disc permissions would work, but I can't get that far. I've attached a few diagnostic screenshots: the first shows a basic diagnostic with "no problems"; the second shows "extended" testing suggesting "HDD Error"; the third shows another "extended" test with my primary HD removed and my blank HD in the first slot and again reports "no problems". Therefore, extended testing shows an error in my main HD and, as you can see, the display is normal and free of artifacts.
