I suppose the obvious answer is to try overclocking it less.
People can not help you if you do not give them the information they need to
help you. what type of ram are you using, have you tested your ram to see
if it is working properly, how much are you increasing cpu speed and are you
adjusting the voltages?
Assuming you have a multiplier locked duron at default 12x133=1596Mhz. Then
12 x 150 = 1800mhz and 12x166 = 1922mhz, these speeds will probably need an
increase in vcore. It also depends if the cpu is an 'A' core cpuid 680 or a
'B' core cpuid 681, as 1922mhz at 1.85v vcore is about the stable limit of
my XP 1800+ 'A' core. Whereas a 'B' core should easily go much faster, at
least 2200mhz with less voltage
The pfn error suggests that the problem is memory / driver related and its
temporary nature that the fsb/memory is being set too high - or there is not
enough vcore for the cpu - however, you have a KT400 chipset you will
probably not be able to get much over 180Mhz fsb top speed anyway so it is
unlikely to be fsb as you are within limits and therefore it is most likely
either memory or cpu (vcore), also is your ram running at the same speed as
your fsb or at +33% which may run it too fast
Perhaps these may be of some help, depending on how good your English is.
