if you pull out the ram and boot does the mobo beep at you?

pulled out ram and powered on but no beeps

I'm think the motherboard is gone.
it should be beeping and letting you know you forgot the RAM.

not good. the only thing i haven't done is replace the cosmos battery. do you think this would help.
the pc has been sitting for a month and hasn't been used till now.

cmos. Complimentary Metal Oxide Semiconductor
it's worth a try. have a voltmeter? the battery should read three volts. if less yeah replace.
