Re: P4C800 Deluxe "Overclocking failed", random shutdowns during startup

I don't know if this is your problem since yours has been running so
long but this is something I looked out for when installing my CPU.

This is part of an article from a tech site from 2003

Here is the link if you want to read all the posts. Just search the

Hello everyone, this is my first time posting into this forum. I came
across this topic from a Google search while trying to find out why my
co-workers and myself have been having so many problems with the Asus
P4C800 Deluxe model motherboard as we have had an excellent track
record with Asus in the past. However, since we moved to this
platform, we have had stacks of motherboards that will run for a while
and then fail to post, refuse to install, and so on.

Now we are using 300W and 350W power supplies and stock P4 CPU fans.
Not to mention that some of the mounting brackets for the CPU fans
needed to be tightened as the were so loose they were falling off of
the board. However, I think we have discovered that the source of our
problems is not from the CPU heatsink being too tight, but rather a
mistake on Asus' part during manufacturing.

I do not know what compelled my co-worker to do this, but he took one
of the supposedly "dead" boards and removed the CPU heatsink mounting
bracket to get a good look at the circuitry. There, located beneath
the bracket on the underside of the board, he found the problem. There
is a small glob of solder located beneath where the bracket sits that,
when pressure from the bracket is applied, shorts the motherboard.
Upon cleaning the glob from the contact and resoldering it, the board
now runs perfectly fine with the 350W power supply we have testing.

Hi,

I am running a P4 3.2 GHz on a P4C800 Deluxe mobo without any problems since
two years.

Since about 2 weeks ago I am experiencing random shutdowns during startup.
When the machine reaches the Win XP desktop it just shuts down after say 10
seconds. Then, when I restart it, I get a BIOS message to the effect that
"Overclocking failed. Press F1 to ... or F2" etc.

I then just turn the power off and boot up again, and usually the machine is
fine after that.

Now, I am not overclocking, so what is going on here? I have not made any
changes to the system just before this started happening. CPU fan speeds and
temps etc are fine and I have cleaned the case from dust.

These shutdowns occur almost daily, always during the startup cycle, never
when Windows has been up and running for more than say 1 minute.

Any suggestions and help greatly appreciated.
