CPU Fan Turning Off

[Guest]

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

My CPU fan turns off when I turn my computer on. If I reset computer
everything is fine. Does this everytime. I have tried all the bios stuff and
reinstalling XP. I think Motherboard but not sure. System is AMD Athalon 64,
K8Ns Pro Motherboard, LG DVD Writer (which does not work right either. Not
sure if connected to problem) Games run great and no problem watching DVDs or
anything. My system does not overheat, or crash unexpectedly (once i a while)
so the only real problem is the cpu fan turning off at start. Wierd.... Would
love any thoughts

This is a long shot, but you might check to see if the
wires from the fan are connected firmly to the fan header
on the motherboard... and if it is connected correctly,
see if you can connect it to MAYBE the power supply fan
header if its long enough, for testing, but I doubt it.
All depends on the motherboard location of the power
supply header, if it has one.

Last resort is to buy another fan and install it. After
that I don't know. Almost sounds like a APM (Advanced
Power Management) feature/problem.

When you say it crashes once in a while? How often is
that? Once a month? Once a week? You might even look at a
good power supply as a VERY last resort... like Antec 350
or greater.

If the fan does spin up in some time after a cold boot, this must be the
BIOS feature which waits until your AMD CPU temperature would reach some
threshold. Power-on spin-up and -down is a circuitry check.
