How is the computer on 2nd floor connecting to your hub/switch? Is it a direct run? Is there a cross connect? Is there a patch panel on the 2nd floor?

If you tried the PC in your office and it works, then its not the PC.

If you take your working PC and (what I assume is a working patch cable) up to 2nd and it fails. Then it sounds like a cabling issue to me.

You would need a cable tester to shoot the line and look for loss of connectivity, crossed pairs, shorted pairs, etc....
