Hi Herian,
Excellent. Your problem is resolved. As you know windows crashes maybe relarted hardware or software error.
I've summaries all the analysis report of all your dumps. Your version of nVidia and Zone Alarm has BSOD record. This is the first time I find IRQL 7 crashes with BSOD. In addition TCPIP is a stable module and it is unlikley to crash unless it is software. Maybe the caller passes invalid parameter to TCPIP and crash windows. This is reason I think it is hardware record. I will be aware if similar problem occurs, it may be software problem.
You installed too many software which are high risk software. From your minidump you installed Zone Alarm, Symantec AV and nVidia Display Driver. They are almost the latest version, it may cause a lot of unknown problem. According to experience, those software developer do not well test their software before they release the software patches. Especially ZoneAlarm has a lot of problem.
Maybe you upgrade ZoneAlarm and nVidia Display card driver to the latest version when you re-install windows. You may encounter upgrade ZoneAlarm later when you upgrade ZoneAlarm. Do not assume the latest software resolve the problem as new version of softtware may be incompatible with other software. As the software developer may not test all the different software combination at their lab. You need a stable Windows. If you feel your windows is stable, turn off the auto update.
The following posts are problem relating to a ZoneAlarm. There have a one post in this forum, de-install ZoneAlarm resolve his BSOD problem.
