Help needed (Comp random shutdown)

[colinm1]

Have a problem with comp shutting randomly shutting down for no reason

When I reboot I get message " OVerclocking Failed" please press F1 to enter Bios, press f2 to reset bios to default".

I have never overclocked my PC so do not understand this, has happened 3 times in last 24 hours.

No new software has been installed and the only hard ware change was an upgrade pf my PSU to 500W about 2 months ago.

Have never seen this message before and am stumped, would really appreciate any help or advice.

My specs are:

Pentium 4 - 3.2 Ghz
Asus P4P800Deluxe mobo
1Gb dual channel Ram
500W Antec PSU
Nvidia FX5900XT Graphics
80Gb IBM Deskstar 7200
60Gb Maxtor Diamond 7200
Audigy 2 Soundcard
Toshiba 16x DVD Rom
Pioneer 110d 16x DVD Writer
Samsung Syncmaster 970P 19" TFT

Windows XP Professional +SP2

Thanks

Could be the CMOS battery dying?! I suggest you take it to a PC repair shop, as, although we're all extremely smart, such "remote doctoring" is usually uneffective...

This happens with all Asus Boards nearly..


It is usually a sign of 2 things


1. PSU isnt 100% right.

2. Hardware was changed with power cord still attached to PC.

I had the same problem with my ASUS mainboard, each time after bios update. The solution was to set the bios settings to default, then one complete boot to windows, restart, enter bios, make settings, reboot.
That's it.

Then you don't do it right. The correct and safest way to flash the bios is this:

1. clear CMOS to complete restore original settings and making 100% no settings will be "hardflashed" into the BIOS (happened for me on my NF7-S v2.0 when I forgot to clear CMOS first and ruined the DDR speed settings totally).
2. start the pc and flash the bios in DOS (I never had and never will trust windows flashing utils, DRDOS along the with flashing tools is the way to go).
3. boot up, enter BIOS do "load setup defaults", save&exit
4. enter BIOS again, change settings and enjoy a good flash with no problems...

Also you might want to look at the capacitors on the motherboard itself...If they look like bulging coke cans then that could be a possible culprit also!!!
