Question

I have just installed a 256MB SODIMM card on a Compaq Armada E500 laptop. On first boot up the laptop will not boot and I am getting an intermittent sound like an alarm.I didn't have the user manual as the laptop was bought second hand and I removed the back of the laptop to find the SODIMM location. I eventually found them behind the keyboard.Can you advise what to do to resolve this?
