Vista freezing by Torrent and Lan access

Do you have the latest drivers for your network card?

yes...got it from VIA. didn't use the windows driver. but still got these freezing problem.

Does the MOBO have two on-board network cards? If so, then try the other one. If not then maybe try another card.

As an experiment you might try:

1. working in safe mode
2. Disabling AV software temporarily


Does the PC need to be restarted after the freeze or does it come back?

Purchased a $5 NIC and my problem is solved. Thanks!
