Performa 550 ??

I second the PRAM (Parameter RAM) battery fix. Also, if you turn the machine
on, it powers up then nothing, if you do a hard reset once or twice it
should boot normally, but with all PRAM settings set to default (IE clock
set to "Date of Antiquity") After replacing the PRAM battery, make sure to
zap your PRAM at first boot to get a clean default setup by holding down
command-option-p-r (I think) on first boot. Let it reset three times, then
let it boot.

Hey, at least they behave better than when those old Sun NVRAM clockchip
batteries die :)
