    Specs:
    Intel Core i3 330M
    4 GB DDR3
    GPU ATi RADEON MOBILITY HD 5145 512MB
    HDD SEAGATE ST9500325A

    How does it manifest: system freeze while watching youtube videos or skype video chating.
    How i tested the system: prime95 for 48h (without pause), aida64 system stability test for another 48h (without pause), 3dmark, furmark, memtest86+, hdtunepro
    It passed all the tests, but it keeps freezing (I already tried to reinstall the OS - windows 7 home premium 64b).
    It's kind of anoying because it doesn't do it all the time, it can happen twice in 5 min, and it can happen once in two weeks.
    No other apps installed, just firefox, adobe reader and skype. The internet connection is from a usb modem using 3g dial up service.
    It doesn't create minidump file, it doesn't show a bluescreen, it just freezes.

    yes, i did that. i assume its a chipset/cpu/power problem. cpu specs say that max tdp for my cpu is 35w. aida64 showed some peaks, some of them >100w. i don't know how accurate is this, but i think the mb goes into protection mode if something goes wrong. i underclocked the cpu using windows power management at 90% in maximun cpu speed and seems to go smoother now (no more peaks ... for the moment).
    i finished testing, now i'm using the laptop in a normal, non brutal way.
