[QUOTE="MacInWin, post: 1743447"] It sounds like either a logic board problem, or maybe a memory issue. Given you can reboot from the CD, do that and then STOP at that point. Don't try to install. There should be a "Utilities" menu and the logo in the upper left corner. Use the to get to About This Mac and get the model information from there. Yes, I know you said maybe 2012, but get the actual version. Once you have that information, post back with that here. Then you can try reseating your memory chips and cards. You said it's a Mac Pro, which is a desktop, so you can try reseating the cards to see if any are not making good contact. Finally, reboot from the CD again and this time don't run the installer, just use Disk Utility to see if you can check the HD. The fact it can boot from the CD is encouraging, sort of pointing to something encountered later on in the boot process, like a memory chip failure or a drive problem in some other area of the disk(s).
