Hi Zephyroth, I labelled the volume in one word in the new installation with GUID. The same problem occured however instead of blinking cursor it shows h0 error. Also, when told the system to shutdown in the O/S, the screen shows hold tyhe power button for several seconds or press the reset button. Is this normal? Or can this be another problem?

Please let me know, thank you. I appreciate your support.

PS: About this Mac, is the processor info suppose to accurately show with AMD, etc? I had to manually change the info.
