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

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.

Have seen this happen when UPS batteries become old and not
supporting a cold start of the computer while the UPS circuits
stabilize the mains.

If not using a UPS, then the PSU becomes suspect, especially
when it is less than 400 Watts for a system like the P4C800.
