Ok i'm getting BSOD with a reference to NDISYS driver. Im pretty sure thats a network card related driver. So my first move was to update the driver for the network card we have. The errors continued. Not surprising as we never use the network card as our internet connection is directly through a usb adsl modem. So just in case I updated the drivers for the modem (D-link DSL-200). Didnt help. Next move was to change to two new (well borrowed, virtually new) sticks of RAM. Still the errors continue. I dont think its memory related as the errors only occur while using Limewire and BT clients. I use utorrent and that uses like 5mb of memory so that bugs me even more. I've included last 6 minidumps (attached). Any help would be appreciated. Specs: P4 2.8ghz HT 2x512mb generic ram windows xp sp1 nothing is overclocked.
