Fucked up bandwidth question

I'm supposed to be getting 1mb/s upstream, and on most of my computers I do. Those computers will build up to full speed over about 15 seconds and then maintain it. My main computer does something different. On this computer, it builds up to 600kbps and maintains it for 20-30 seconds before dropping down to 300kbps where it stays. I'm running vista 64, and I've hunted around trying to see if anything was actually using that bandwidth, but the consistent drop makes me think the problem is somewhere else.

Any ideas?

    ISP?
    Network setup?
    Methods of testing?
    Computer specs having issues?
    Number of computers not having the issues?

    AT&T fiber optic
    their router -> my router -> 3-4 pcs
    intel c2d e8200
    4gb ram
    8600gts 512mb
    Gigabyte GA-EP35-DS3R (I am using the integrated nic)

    I've tested with speakeasy and dslreports with the exact same results.
    I tried swapping cables, I'm pretty sure it isn't the router because my other computers are fine. My other computers are running vista 32 and xp home pro sp3. I haven't tried using older drivers for the NIC yet, so I guess I'll probably try that next.

    When testing the computer having the issues have you unhooked the other computers from the network so as to be sure they aren't interfering with the results?

    I did try connecting my computer directly to the giant router with no other pcs connected.

    Are your system specs pegging out when you run the test, cpu or memory, they're normally java which can take more resources.

    They barely move from idle readings. The driver finally got finished downloading from gigabyte, so I'll check that now.

    If that doesn't work take it into safe mode with networking and run the test.

    Works fine in safe mode, so I guess I just have to figure out what the hell I've got installed that's fucking me over. I guess I'm leaning toward the unsigned drivers necessary to run peerguardian, but who knows.

    Okay, not one of my better days. Turns out some bandwidth manager I'd installed a while back (to keep the WoW downloader from saturating my line) actually ALSO runs as a service. So that was still getting loaded at boot, etc. At any rate, thanks for the help.
