Here's one for the books, if anyone has any idea what I did wrong, I would
be curious to know, as I don't want this to happen again.

I had an A7N8X Deluxe version 1.4. Had always been rock solid for me. I
was
running an Athlon XP2400+ in it, and decided to drop an Athlon XP 2600+
Barton in it, since the prices were so reasonable now.

I hve built many computers, and upgraded cpu's many times with no
problems.
So I get the new chip, install it, install a Thermalrite SLK900 heatsink
w/
92mm fan, using Arctic Silver 3.
Turned it on, immediately went into bios to correctly set the fsb. Exited
saving changes, and it started to boot, then gave some error message about
cpu changing, then shut itself off.
Try as I might, I could not get it to post again. I would turn it on, the
hdd activity light would stay solid, and it would not even post. I checked
all my connections, verified everything was correct, still no go. I
reseated
all my cards and ram, no go. I took everything out but video card, no go.
I
tried clearing the cmos, still no go.
No post, no beeps, nothing. Monitor's power led was orange rather than
green, so it obviously was not getting a signal.
Treid replacing the cmos battery, and clearing it again - still , no post.
Tried putting the XP2400+ chip back in, to make sure the new Barton chip
was
not bad. Still, no post..

At a loss, I figured I must have somehow fried my motherboard. So, I orded
a
new A7N8X Deluxe version 2, and had it overnighted in from Newegg.com.
Put the new motherboard in, hooked everything up, including putting my new
Barton 2600+ with SLK 900 h/s, and she posted and booted just fine, and
has
been running fine for the last 4 hours so far.

What in the world could have happened? This one has me stumped.
I did everthing correct, so I thought. I did it like I always do. I never
could get that mb to post again.

I am just curious, any ideas on what may have gone wrong? Seems like I
remember reading on these forums some cmos issue these earlier boards had
that could render them dead maybe??


OH, and one last question. I installed the Asus drivers off the included
cd
rom. Any advantage to updating to the newer drivers from Nvidia.com?

Thanks,

I had a computer one time that would lock up only when running a certain
program and then when doing a certain operation. The problem got worse over
a period of a few months but only when I ran that program(auto sketch). I
had several other programs that I regularly used that caused no problems.
Finally the whole computer locked up. I tried everything to find the problem
and while in the process of reinstalling the operating system I discovered
that if the computer was rebooted after running, about 50% of the time I
would get memory errors on the POST and if I shut the computer off for few
seconds the memory would pass the POST. I replaced the memory and the
problem never returned.

A ram memory error would show up on the post(AFAIK). The point I am trying
to make is that not only changing the CPU but certain programs can burn up
the MB if you have marginal chips on them. ASUS's are high quality MBs but
even so how many are used with the Athlon XP 2600+?
Is someone pushing the limit? Is the broken MB still on warrantee?
