Could it be CPU, MB or PSU? How to fix? Can I replace one P4 with another scavenged one? Any advice greatly appreciated :) I've tried Google, but haven't found much.
My 3.2GHz P4 (not OC AFAIK) is reaching 92°C within a minute or two of starting up (in BIOS setup's temperature/voltage monitor), before turning itself off. Either that, or the temperature sensor is faulty.
I've tried cleaning dust from the heatsink, and then tried cleaning and reapplying the thermal paste between the heatsink and the CPU. The voltages are all apparently more or less as they should be.
I have another P4 from another dead computer. It has a different spec., but I think the socket is the same. Can I use it as a replacement? Is it just a case of plugging it in (w/ heatsink, fan)?
It started cutting out during heavy processing, got more and more frequent, faint beeping sounds coming from somewhere (not the fan).
Thanks for your input.
