[quote]UPDATE!
BIOS (why didnt think of that before?) says my CPU is currently hovering around the 60c mark which would make sense for a P4 Prescott..
So it seems those who thought that my CPU and Northbridge temperatures were inverted were right.
My sensors are t*ts up.
At least I know now, and I dont need a new motherboard thank God (funds are limited at the mo).
Later today I'll be reseating my CPU heatsink with some new thermal paste and if that works I'll leave it alone for the moment.
As has been said so much recently, I'm gonna wait before I spend on serious upgrading!
Thanks for all of your help lads, Ive learnt a lot from this episode, I'll keep you updated!
Rob.
