Why is internet slow on reinstalled XP?

Specs: Windows XP, Athlon XP 2400+/1 GB
I recently upgraded the hardware on a Windows XP box and felt it would be best to reinstall the OS as well. After doing so I installed the drivers and updated XP to SP3. I am running almost a bare-bones system at the moment. I have installed one game plus firefox and some media codecs but nothing else. All these programs (and more) were installed on the system before the reinstall but suddenly I am noticing a huge drop in the internet connection speed. As per my ISP my connection rate is 3 Mbps. I usually get anywhere from 3.0-3.4 Mbps using http://www.speakeasy.net/speedtest. But now after the reinstall I can't get above 1.2 Mbps. I entered services.msc and disabled Automatic Updates and Background Intelligent Transfer plus Windows Firewall to see if perhaps that was causing the problem. This was all to no avail. I really have no clue now what is the matter? I contacted my ISP and they walked me through a hard reset for my cable modem but it didn't help either. I am at a loss. My internet is not supposed to be this slow and the tech support people with my ISP don't seem to have any other suggestions that I didn't already try.

Please help me.

airwalkrr, pure SWAG, take a look at what you have running in the background in your start menu. My guess is that M$ put extras there with SP3. There're certain 'musts' that have to be there and I have links to lists if you need 'em. There're other 'maybes' if that doesn't do it. Just post back if you need 'em.

I can't possibly imagine what it would be in SP3 that is causing my speed tests to come up so slow.

On another note, I have run speedtest.net and a speed test provided by my ISP and I continue to have issues. I spoke with tech support with my ISP today and it turns out I am supposed to have a 7 Mbps connection (they upgraded me and I wasn't aware of it; rather nice of them). So there is even more of a problem than I thought. At tech support they said it might be a hardware issue so they offered to swap out the modem. I already swapped out ethernet cables and that isn't the issue. I am using the integrated ethernet on my motherboard. I tried to plug in an old ethernet card and try that out but apparently it isn't working anymore so maybe the integrated ethernet is somehow faulty, but that seems unlikely. So I will pick up a new modem tomorrow. Aside from that, is there a way to test my ethernet port directly and see if there is something wrong with it?

Well perhaps this sounds silly, but I found the problem. Apparently it is my integrated ethernet that is the culprit, although I haven't heard of integrated ethernet slowing down without breaking completely before. Even though the old ethernet card I tried was broken, I came up with another idea. Rather than connecting directly to the modem or router, I plugged in a wireless ethernet adapter from another computer and tried connecting to the router. Turns out my speed is just fine after that (about 20 Mbps). I never thought to try wireless before since wired connections are usually faster, but lo and behold, the wireless connection works great. So I guess I'll be needing a new ethernet adapter.
