One of my XP SP2 based PC's reboots itself a couple times a day. It doesn't seem to corelate to any particular application. Several of the crashes refer to tcp/ip stack drivers and several refer to win32k.dll.
Disabled a few services, uninstalled a few programs. Run both Ad-Aware and Seach & Destroy and Norton Antivirus to clean the machine.
I've also run Prime95 for 6 hours without finding any errors. I've tried reading the minidumps but don't know how to use the info provided. Any help would be appreciated.
Here is a link to a zipfile with several minidumps:
