Mac Pro tower 2006 2,1
I got a Mac Pro and been installing MacOS lion and it kept giving me a problem that I bypassed. Turns out every time the Mac restarts, whether on command or on its own, it hangs up, remains on but never outputs video nor does it do the boot chime. Of course, I can overcome the problem by simply turning the Mac off then on again, but that’s the problem it has. I replaced the cmos battery and pressed the button on the board, and it did work after 2 times of restarting it. After changing the time and letting the PC hang, I restart it and it went back to doing the same thing. What’s the problem with it?
