hmmm, that video card isn't much (as in its 3-4 generations old), but your processor is old as well.
I think that mobo on your specs accepts Phenom IIs. Even a Phenom II 550BE would give you a good boost ($90):
your current processor vs 550BE...
try removing stuff and testing them one by one. test one video card at a time, then start adding components until you get a beep or an error message. remove all unnecessary USB for now.
what motherboard is this on?
So did you plug in the ATX 4 pin as well?
Do the fans spin at all (does it stay spinning and the screen is just black?), check if he has a microphone attached to the motherboard for beeping, some cases don't come with a beeping speaker.
That sucks. Cases usually are shipped in double boxes. They must be really careless to do that too because the ATCS is pretty tough. ugh, I can only imagine how annoying that is finally getting your shipment then finding out its damaged.
The disturbing thing about this is the totalitarian aspect of the iPad with all the software for it has to be approved by Apple (not to mention hardware and accessories customization as well), kinda ironic since Apple had that now iconic 1984-style commercial.
I just started playing ME1 last night, no hassles so far other than it would crash on save sometimes and the shadows on the faces kind of bother me (it flickers a lot). This looks like a long game. lol, it will probably take me a month to finish.
If you are going for 500GB, Samsung F3s are single platter I think (so are Seagates new 500GB IIRC)
If you are going for 640GB, Caviar Blacks from Western Digital have dual platters, 5 year warranty, 32MB cache, etc.
