CPU is unworkable or has been changed. Please recheck - CPU SOFT MENU"

I've recently changed the power supply of my computer and when I boot up I get an error message "CPU is unworkable or has been changed.  Please recheck - CPU SOFT MENU".

When I press F1 it starts windows normally but after about 2 or 3 mins. it reboot itself and back to the error message.  I have a Abit IC7-MAX3, Intel P4 2.40ghz.  Please help.

Thank you,

Try clearing your BIOS. Maybe your previous settings didnt like the new PSU output.

Also some power supplies are known with their competibility issues with certain boards, like antec neo series.. What brand PSU did you get ?

Have you tried putting the old power supply back in?  Perhaps the new one is causing a problem with too little or too much voltage to the CPU
And look at replacing the battery on your motherboard..

It may be dying and not holding the settings.  This is what I suspect is the origin of your error message.

check what you need here :    http://www.jscustompcs.com/power_supply/      
was ther e a 4-pin power plug connected? and did you connect it on the new one too?
Is your computer homebuilt or made by a big brand company (i.e. Dell)?

Dell, Compaq & IBM are notorious for using Proprietary (non-standard) power supplies in computers.  If you happen to be unlucky enough to have one of these computers you will need to return that new PSU and call your vendor for the correct part.
Review the cpu/fsb/ddr settings in bios; if set to 'manual' try auto, if set to auto, try manual (make sure to use right fsb/multi). This usually fixes this kind of error. As for the cause, could be an overload on +12 or +5 rail but also cpu or ram...

I bought a brand new PSU (compatability issue) with a higher wattage and I also changed the battery on the motherboard, and It Works!!
