My Vista is Slow During Fast Downloads

I'm running a pretty new laptop: Vista Home Premium on a Core 2 Duo (1.83
GHz, 2 MB L2 cache, 667 FSB) with 3GB RAM. When I download files at speeds of
about 100 kb/sec or above (in Firefox, uTorrent, Miro, etc), my computer goes
noticeably slower overall. There's significant delay when I move the mouse
around the screen and such. This doesn't always happen, at least not on a
fresh reboot, but it's not long before the problem comes up.

From looking at the task manager, there's no other processes sucking up the
CPU, the temperature of each core is around 50 degrees C, and almost half my
RAM is free. I haven't seen information anywhere on this specific problem,
but I've tried a number of the steps recommended to help improve Vista's
performance to no avail.

Any advice?

Thanks,

Elton

Elton,

one possible cause could be the network adapter eating up
interrupt response processor cycles. It could be defective or
poorly designed, or there could be a driver or interrupt
hardware problem.

Try to investigate in these directions.
