uTorrent hogs 100% of my connection

Sounds like it's swapping out... Or Virtual Memory I believe they call it on Windows.

Shouldn't be a memory problem I don't think.
I have 4gb of physical memory, and have an 8gb pagefile, as well as a 2gb flash drive running ReadyBoost.
I am going to try removing the flash drive, and leaving the pagefile on system managed, and see if that makes any difference.

I had this problem and to fix it I limited by upload to about half of what it can achieve and also took a bunch of inactive torrents out of my seedlist. I found that the more torrents I was uploading(even if they werent active) would slow down my computer.

I just reread the OP. I would agree that it is most likely not a memory issue.

I would reset uTorrents settings to default and see if it persists. If it does, I would start to back things down in increments of 10%
