Yah. Mac Test Pro comes up clean. Hardware test is clean. All the
utilities that I use to shoot customers Mac's give it a clean bill of
health. I Am thinking PS too. I just can't prove it. I would really
rather prove it during a service call to Apple so that I don't have to
order the PS out of my own pocket. I am an authorized Tech and Reseller,
so I could just order the part, but I don't want to pay for it since it is
still under warranty.
I tried replacing the video card, and I have used 3 different HD's in the
machine. Same symptoms. This is beginning to piss me off. Usually I can
find the answer/problem in a matter of minutes, but this has been going on
for a month. Aaarrgh.
