I just found my crappy old acer laptop, 1.5GHz Celeron M processor 1gig DDR2 Ram. From what I remember of this laptop was it kept freezing randomly. To get it working again all power needed to be cut then it would reboot but then would freeze again in a slightly shorter time.
Is this due to heat? I ask this as there seems to be no thermal paste in the chip at all. Or is it bad memory?
