Default bios 1 beep then continuous until shutdown

hi,

i am troubleshooting a motherboard. Bios: Phoenix. Symptoms: During
Power on. it beeps once (normal beep) then bios and cpu informations
are displayed on the screen. As well as the message to press Del to
enter setup. At this point, the computer hangs and beeps continously
without pause until I turn the computer off. What I did so far were,
place a silicon grease (heat sink cream) b/w cpu and heatsink. Memory
was replaced. But the problem was not solved. I am thinking of a bad
power supply now. But let me ask first if someone had already came
across with this problem and can give me some troubleshooting guide.
thanks in advance.

ian
