thats too high .. by around 10C-15C for midtower/full cases

a P4 should be running at about 30-35C ... in idle
i think your either your heatsink is bad or your fan is not spinning right
amd XP runs about 5-10C higher ...
cpu temps are highly dependant upon:
- good seal between heatsink and cpu ( use good thermal grease )
- good thermal coefficents between air and the heatsink to pull
the heat off the heatsink
- cpu w/ copper heatsinks are a bitch to keep cool since
copper is a good thermal conductor
- good streaming air flow across the cpu heatsinks
- number of heatsink fins also effects the cpu temp as does the
thickness of the heatsink on the cpu
all temps from bios "pc health monitor" vs lmsensors ( can be way off )
you're killing your CPU at half-life rates for every 10C increase in cpu
temp from 25C

memtest does NOT prove that memory is bad ...
- you can have a timing problem between mb and mem modules
- you can have timing problems between mem modules
- you can have cpu/motherboards running fsb-200 vs fsb-333 vs fsb-400 vs
fsb-533 vs fsb-800 and the corresponding memory fsb

pci buss speeds
-- use a different/better memory stick ... usully is 10x more reliable of
an answer if the "system works" or not
( use kingstron, mushkin, corsair, memory sticks
( use lei, century, atp, etc...
- no manufacturers label or if their mem prices is 1/2 of
kingston/mushkin/corsair... than you've potentiall got a memory
problem out of the box
