Hey guys got a new one. Old gateway tried to put more memory in and nothing happened so the old memory was put back in and now all it does is beep 3 times. It is running in the background just no video now any suggestions?
its a RAM failure... either the actual modules or the slots on the motherboard. best way to test it to chuck the modules in your own pc and see if they work, if not, replace them, if so, new motherboard.
dont lose all hope yet, if you have more than one memory module, try changing slots a few times as it sometimes works when they are in a different order.
