Hello Wedgeling, and thanks for the welcome.
I'm not a new user, actually. Been with PCLinuxOS for about three years and was a member of this forum for about two years.
Cancelled my membership a few months ago but back now (with a reset of my postings to 0, but that's only fair).
Hardware is P4 3.4, 4Gb ram, Nvidia GeForce 9500GT 1Gb ram, motherboard Intel D945G.
Never had the overheating problem you mention.
