Mac Pro running Hardware Test

is that a hard smc reset?

Apple does not suggest holding the power button during reset, but many others feel that it is the proper way to do it----to ensure that the reset actually happens, I suppose.

It's worth trying if you haven't ever done it that way. It won't damage anything.

2008's and early versions of ML were a bit finiky for some systems.

Use Option key and Startup Disk to change over.

If you upgraded to ML over a system that had Snow Leopard, that alone can leave a lot of 'stuff' carried around for years, out of date, or incompatibile - and Lion is where Rosetta was removed and support for Power code.

Apple has changed the directions for SMC Reset with every model, and rather than "use this for that model" or have links to changes in tech notes... even old developer documents that use to be public... gone now. They helped understand FBDIMMs for some of us when Mac Pro debuted.

sorry to be an idiot... but could you kindly explain the process?

Proscess For SMC reset?

Turn off Mac Pro. Unplug power cable from the wall. Unplug all peripherals. Press and hold power button for 10-15 seconds. Release power button. Reconnect all peripherals. Plug Mac Pro back into wall socket. Wait 10 seconds. Power it back on.

Create an OS X Lion Install disc

First, make a backup copy of the ML install app. Once you run it, it disappears.

To install ML from SL, you can try launching the App (located in your Applications folder, I believe) from within Snow Leopard. The interface that comes up should present you with options of where to install.

Choose the install location (hopefully you've prepared another partition on another drive in your system), and let it install.

Snow Leopard will be preserved and your 'destination' drive will have ML on it.

And upgrading from SL to Mountain has risks, is dirty if you will, and you want to retain a working system.

Save it so you aren't faced with another download, time if nothing else.

My ISP instituted 'caps' for various plans, that come out to about 4GB per day, generous for most.

Was there something I left out?

Pressing the power button with AC power removed is intended to guarantee that the power capacitors in the power supply are completely drained. Various chips in the system are thus guaranteed to recognize that power has been completely removed, and when power is applied again, a complete Hardware Reset is assured.

Thank you for the clarification. I'm glad to now know what exactly it is I'm doing when holding down that power button.

It will work.

What do you guys think of this drive for the mac as a boot drive?

my ram is not installed in the right order.

If you know it is not right, then fix it! It is not difficult.

If you still have the problem, but have no more things to try, then it is time for professional help.
