OK here is the situation:

We have a basic home network, with 3 computers and an xbox connected via a 16port switch. A Motorola cable modem is connected to a D-Link router/gateway which is connected to the switch. The router is our DHCP server.

On Sunday I built a computer for my flatmate out of donated parts (brother moving overseas). The computer seemed flakey at first, but now it's running ok (no more crashes/stop errors).

The only problem is when browsing the web. He can view webpages for 1-2 minutes before they stop being displayed. Firefox will just bring up a blank page and say done in the lower right corner. MSN and Gtalk will stay connected, so there isn't an interuption of service or anything.

As far as I know the CPU (AMD Thunderbird 1k) is fine, but can swap for a 900 if I have to. The ram is fine as far as I know, and I wouldn't think it would cause these errors. I have tried two different network cards (generic realtek and 3com etherlink) but the problem persists.

Anyone have any ideas ?

All I can think of is to check and make sure that you have the proper number of DHCP clients in the router. For example, the router could be set to recognize 4 DHCP clients (your 3 comps + xbox) and it doesn't know there should be 5 now.

I know on my Linksys there is a place to set this, but I've never owned a D-Link so I don't know how those work.

Other than that, theres always the good old format C: and start over.

Network debugging:

Bring up a command prompt window.
Type: ipconfig /all
Check out IP address, gateway address, DNS address, make sure they are sane.
(If not sane, try: ipconfig /release then: ipconfig /renew and then check again as above.)
Type: ping <default gateway IP address>
If that works, you have basic connectivity to your gateway (probably your router).
Type: ping <primary DNS address>
If that works, type: ping yahoo.com
If that works, you have DNS working.

If that doesn't work, log into your router and check gateway, DNS addresses from there.

If all that works, then check your application configuration.

Can ping other PC's on the network, can ping router, can tracert www.google.com

But no web pages. Might be a DNS issue, works for 5 minutes then it will stop. Weird.

Try hard coding the DNS.

Long shots:
- Updated drivers for the network card.
- Bump the card down to 10mbps/half duplex. (Device Manager > Card Properties > Advanced tab)
