Answer 1

that means theres a error , make sure you installed any part of the computer correctly :D or make sure you placed the motherboard the right way and closed the computer case correctly!

Answer 2

if the beeb starts right after you installed the memory stik . the problem is from the ram , take the new ram out the slot.put the old one in place. restart the pc , if the beeb gone . the new ram either bad or is not well installed in the slot. that's happen. next time take with you the old one to store and there match it with the new one you choose to buy.
