Mac Pro and hanging

[SDAVE]

I have a 2007 mac pro and when I try to run OS X, I get the Apple logo then the spinning wheel during the grey screen and it just crashes (BSOD?)

I tried to install a new version of OSX but I still get the crash. Tried a new hard drive, new ram, but still no go.

I have a feeling its the video card, but if it was, i wouldn't even get a signal, right?

What happened before was that I was able to install a new version of Snow Leopard and it worked fine, then overtime it just froze again and now it always freezes. Can't even go into boot mode to install Lion from scratch.

It's funny because I have a 2008 Mac Pro and it has never given me problems.

I have a feeling its the logic board and it would cost a lot of money to replace that. The machine is probably valued at $800 right now since it's from 2007 and I think the logic board might be around $500.
