They mean ten business days, which makes it longer
I finally got the motherboard back but they reported that the motherboard tested fine. I took it to a computer shop this afternoon, and he discovered that it is something with the burned copy of windows xp pro that i was using. He put a new copy in and did quick install and it installed within 5 minutes! He also burned service pack 2 on a cd. So im going to try my copy in quick install and if it doesn't install like the other copy im going to have to by a licensed copy.
