I recently format my custom built pc with windows xp pro service pack 2 and have been experiencing random errors/restarts that give me the BSOD. The BSOD do not correspond to any games or videos that I am using they usually occur while web surfing. I have been unable to find a solution to this problem. Any help would be appreciated.

I tried to look at my minidumps but wasn't able to open/make any sense out of them. I attached the 4 of them that were in \windows\minidump

Your crashes are caused by various bugchecks, including memory corruption, bad pool caller and one crash by "afd.sys", which is part of Windows Winsock driver. First follow the instructions in this post: http://www.techspot.com/vb/topic51365.html, and post back here.

I went through the instructions in the post you gave me and nothing so far as solved the problem. I doubled checked that it could not be overheating ...dust on heatsinks/power supply failure or ram problem. I have not added any new hardware and as I said in my first post I just formatted and installed a clean install of windows XP PRO service pack 2. Just the other night I was about to shut down and closed out all of my explorer windows/firefox tabs and it did a restart. Is there anyway to update/replace the Windows Winsock drive (afd.sys) Any help/suggestions would be appreciated. I attached a zip with my updated minidumps(including the one that was created from the other night).

one crash caused by pool corruption, one by "afd.sys", one by memory corruption, and one by "ntkrnlpa.exe."

The Winsock Fixer is available here:http://www.snapfiles.com/get/winsockxpfix.html. Did you try running your pc with only one stick of ram, and did any of the crashes happen while running Half Life 2 and Avant Browser??

I thought I had the problem solved and I didn't get any reboots for 5 days or so and then tonight I got another one with the same error. Yes the reboots have occured while running avant browser and Half Life 2 (counterstrike). What is the significance of that?
