Though not impossible...a dead battery usually does not prevent a
machine from booting...simply the cmos settings are lost.
It cannot hurt to try a new battery though....and also resetting the
cmos by using the jumper
As mentioned elsewhere...if the capacitors on the mobo are bad
it's not worth going any further.
Good chance it's just the power supply though
