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

Hi,

Thanks for replying. Please indicate how a PSU problem may arise so
suddenly, without any hardware changes. Also, why would a PSU problem cause
the "Overclocking failed" message from the BIOS.

All the best,

Magnus

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.

I would start by trying a different power supply.

The shutdown could be the power supply switching off when
the load from the Windows desktop happens.

Or it could be a motherboard problem, with power_good,
I suppose. (Power_good deasserted due to some problem with
voltage conversion on the motherboard ?) But since power
supply failures are more common than motherboard failures,
start by trying a spare power supply.
