Running a diagnostic on a used Mac Pro

[phaedarus]

Hi,

I'm in the market for a used Mac Pro (this would be my first one since I bought a G4).

Because Mac Pros are a pretty substantial investment, I'd like to be able to test the system to make sure it is in good working condition.

I was thinking of using something like techtool pro to run a diagnostic to check components such as the logic board and memory. However, few sellers seem willing to entertain the idea; perhaps believing that my intent could be malicious.

What is the best way to go about doing this? The last thing I want is to end up with a $2000 lemon.

Thanks.

The only thing I could think of is running a diagnostic using the install disc that came with that unit. After inserting and restarting with the install disc, hit command+D However, I am not sure if the diagnostic test does a check on the videocard. If you're getting the Ist gen 2006 MacPro, watch out for the Nvidia 7300GT videocard. It's a weak card as its capacitor usually dies out. Happy buying.
