Strange Network problem

Hello Everybody!

I have a strange problem. I bought new motherboard ASUS A7V600-X and LAN does not work properly. My PC is connected to small home network with a several PCs and Server. I have a problem with download speed. I chosen a big file (over 150 MB) from Server and i started some tests to find what's wrong.
When I started to download this file to my PC from Server, my Win-XP displayed a message with estimated time of downloading - 30 Minutes. Meanwhile I saw that my 3Com 10/100 Hub (at my desk) shows "Network Utilization" level of 2-3%... little slow. After 10 minuters i cancelled the operation.
I started to download the same file from the same Server using my Notebook connected to the same 3Com HUB. The file was on my Laptop after 30 secs...
I thought that LAN adapter on my PC is down, but I think it's not. Why? I started to download the same file fom my Notebook to PC and the transfer speed was good. I downloaded it to PC form Notebook within 30-35 sec. So i guess that PC LAN controller is OK.
As a last test I started to upload the same file (I renamed the file) from my PC to the same folder at Server. Upload was finished after 40 secs........

Considering:
Download from Server to PC - sucks
Download form Server to Notebook - Excellent
Download from Notebook to PC - Excellent
Upload from PC to Server - Excellent

Can anybody tell me what is wrong?

Help!

PS

Sorry for language. I'm from Europe and I'm not good in English.

I'd start with the basics, change the connections and cables that are being used. Pick a different port on the hub for each device and see if that affects the results. I'd also consider replacing the hub with a switch, just to see if it's a hardware issue with the hub.
