Hi all, I'm new here. My windows xp start to randomly BSOD since months ago. I have read http://www.techspot.com/vb/topic51365.html I have test my ram using memtest with several successful run and it's my new ram. I do not oc my pc, and don't have overheating problem. I 've reformat my pc also. I've check my mobo and I don't find any leaking capacitor. I include my latest 3 oldest dumps here, another 3 in next post. some of the earlier dump indicate that my pc have some problem with norton and zonealarm, I already uninstall all of these program but yesterday I encountered another BSOD which deal with wanarp.sys. Can someone help me to overcome this BSOD problem, as I have finding the culprit for long time. Thanks.
