Hi,

I have an AMD Sempron 2400 CPU with Abit NF7-S2 motherboard.
the machine can work fine for many hours or even few days, but after a
while, mostly on high load it shut down and a siren sound start.
I have to unplug the elecric cord to stop the siren sound, and restart.
I don't think it's an heating problem cause the CPU does not get over 50cel.

I got an used AthlonXP 2500.
when I put it instead of the Sempron CPU it will work for no longer then few
seconds, and again the same problem.
I could start it once for long enough to get into the bios configuration to
check the temperature, and it wasn't more then 45cel before crashing.

Any idea ?
can it be a PSU problem ?

Thanks

Siren sound IS usually CPU overheating. Could be CPU fan too slow if
alarm level is set too low. Are you SURE heat sink is rigt way round. There
is usually a 'step' on the base of the heat sink which has to match the
step on the socket. What heatsink compoundare you using, and how much?
Mike.
 
Alarm level was set to 70cel.
I never saw it getting over 50cel. (I have Motherboard monitor runing all
time)
Any case I put new arctic silver 5 to replcae the original compoundare came
with the heatsink (ThermalTake heatsink and fun)

Now the XP 2500+ CPU works too, and the temperature is about 30cel. on idle
time (It was around 35cel on idle times before)
Hope it won't crash on heavy loads.

Thanks for the help
