Mobo dead if beeps are heard?

it should be fine since alcohol will evapourate

your motherboard should beep when the ram is removed. it should also light up (at least for my asus board)

It's ok as long as you didn't the pins, most likely.

No.

even if you did break the pins, just put the broken pin into the motherboard where the pin should have been inside the socket

if it posts, its good to go. might want to check the speaker connections

Yeah it was laying on newspaper, face up when I was removing the thermal paste with cotton swabs and coffee filter. A little bit of alcohol touched the sides. I did dry it off however. I do not hear anything when the mobo starts up though, unless there is no RAM.
