Hi all ... If willing persons are able to bounce ideas around with me to help troubleshoot this issue it would be appreciated.

The issue I've got is that the BIOS information keeps getting lost at startup. Has only just started to happen and occurs about 7 / 10 starts.

Messages are either "Overclocking Failure - F1 setup / F2 load defaults" OR it will just boot to the wrong drive, where upon I inspect the boot order and all previous changes have been reset to default anyway. Sometimes it will get past post screen and just lie in black screen limbo - but this later symptom has only happened a handful of times and I expect it may be secondary to whatever the main problem is.

I have replaced the MB battery and later, reset CMOS and setup again after these problems first started to occur.

Setup = P4P800-E Deluxe / P4 3.0 / 1.5g / 2 x SATA WDD 120, 1 x IDE WDD 350 / 2 burners / 500W PSU.
SATA's - 1 x XP Pro boot (3rd Master), 1 x partitioned storage(4th Master), IDE - partitioned storage(Prim Slave), burners set to secondary M & S.
Other devices are installed (i.e. media readers, capture cards, etc) but I won't bog you down with them unless you think it specific.
The 3rd Master is the only device in the boot order.
I have cleaned and inspected board, no bulging capacitors, etc ....
Hardware diagnostics suggest all is fine.

This box has given me no trouble to date .... so what do you think?

What brand is your power supply and have you tested it lately?
I had major problems lately with Antec power supplies combined with ASUS motherboards...

You might want to try swapping out with a different power supply, something such as a Cooler Master, Seasonic, or another good quality name brand.

I've had this error many times with ASUS boards and Antec power supplies until I stopped using Antec totally.

Try replacing the power supply and hopefully your problems will go away...
