it's been a while that whenever my download speed in utorrent goes above 100-150 the whole computer slows down to the point of freezing up.   mouse movement become jerky and every program becomes almost unresponsive, but as soon as I close utorrent everything goes back to normal.

my laptop never had lagging to this extent, so I did some experiments to see if I can spot what's causing the problem.


I shutdown every program except utorrent and essential Windows processes, and I found out even when the download speed reached ~350 kB/s mouse movement and everything was smooth.

then I opened Winamp and Firefox and started browsing around then after a short while the music sound from Winamp became choppy, and followed by that the mouse and everything else...

see below for the processes that where running at that time (2nd one was taken several seconds after the fist screenshot)

I also tried this http://www.utorrent.com/faq.php#I_get_v … Torrent.21

but I wasn't able to find out exactly what's the problem because almost all the files that were listed in the Log had high numbers...

*both my Primary and Secondary IDEs are set at "DMA if available"


any help would be much appreciated
