Error message on my Mac Pro Quad Core Dual
I turned on my mac this morning to find it's normal loading screen of grey with the darker grey logo in centre..all normal at this stage. This was followed by a wipe from top to bottom making the background grey a little darker and in the centre the apple logo was replaced by what appeared to be a semi transparent power button symbol with the words. "You need to restart your computer. Hold down the Power button for several seconds or press the restart button"
I have tried this several times to no avail I have also zapped the P RAM again nothing. Can anyone out there help. I have a Mac Pro Quad Core Dual which is only a few months old and is up to date with its system software.
I could be so grateful of any assistance.
Warm regards
