This is something that seems to have defeated the best minds in the UK so
I thought I'd try here...;-)

I have a home assembled PC - about 18 months old - using an Asus A8N5X MB
and an Athlon 64 3000+ CPU. It's mainly used for semi-pro AV work.

*After a year or so of faultless service, it started shutting down at
random. Would usually boot up again ok and carry on. After a few occasions
I took to having PCProbe loaded and noticed the CPU temp would shoot up
just before it shut down. So naturally removed the heatsink/fan, cleaned
and replaced with new thermal transfer compound.

*All was well for a month or so, then the fault started happening earlier
and earlier - sometimes before XP had loaded. The bios power management
page again showed the CPU overheating - going from ambient to overheat in
around a minute. But the heatsink was cool to the touch. ;-)

I was intending to use the shotgun approach and simply replace the MB -
and possibly CPU - but it seems this design of MB is now obsolete so I'd
have to change lots of other things too.

*I've not been able to find any description of how the CPU temp sensing
works let alone any clues on fixing what must be an intermittent fault -
as I've stripped and re-assembled the entire computer, cleaned all
connectors etc, and it's fine again once more. But for how long?...

Any informed guesses?

I inherited a Dell a few years back discarded by the repairperson as
unfixable, which turned out to have as its only fault a CPU fan which
would freeze up randomly. cost $10 for a new one from Radio Shack, and
that was with a new heatsink included.

I'd say you have a very bright future if you can replace a diode inside a
CPU. ;-)

You behave like an excited kid holding a candy bar, you won't eat the

You have a spare processor but wont put it in to make a confirmation.
You come in here asking a tech question and then wont pay heed to
anyones advice. You obviously have no intention of getting to the
bottom of this problem, you're here to needle people who would invest
time in trying to help (for free) and then poke a them endlessly over
some stupid typo (which has been corrected). You appear to have some
superiority complex because you subscribe to usenet. For me, it doesnt
matter which site you're using, what's important is model, sympton and
result.
I hope your new spare processor gets zapped by static while you're
handling it.

Are you referring to me? If so, learn how to post properly. Quote what you
are replying to.

Who said I have a spare processor of the same type that would fit the MB?
I didn't.

It helps if you try reading - and understanding - what has been said in
the thread.

Quite the reverse. My whole intention was to try and understand the
problem. If I didn't want to do that I'd have simply replaced the MB and
CPU.

time in trying to help (for free) and then poke a them endlessly over

FFS, you didn't make a 'typo'. You suggested a coarse of action which was
nonsense and posted that. Then realised how stupid it was and tried to
retract it. Which can't be done.

usenet. For me, it doesnt matter which site you're using, what's

Great. I'd suggest you learn a bit about how news groups work before
getting all superior.

Oh - you've contributed precisely nothing to my knowledge of my particular
motherboard or the resolve of the problem.

Please don't take my critique personally. I don't know you personally. My
comment is aimed at ALL those that disregard the proper rules of netiquet.

You posted twice. This indicates that you are unfamiliar with your equipment
and how to use it to post to usenet via google groups.

You post to usenet without quoting the material to which you are replying.
Your post is seen without any context by those of us that do not use Google
groups, making your comments useless.

You and many users of google groups are like children that come into a movie
theater in the middle of the movie and treat the theater like their home,
running up and down the isles, jumping over seats, shouting comments to their
friends, grabing a handful of my popcorn and taking a sip out of my drink.

YOUR behavior is rude.

This is usenet. You happen to be using google groups to read a usenet
newsgroup.

The group has its own set of rules, called the FAQs. Read those rules before
you post to the group.
