When I turn on my computer the lifts turn on, fans spin but I get nothing on the screen. I have tried a different hdmi cable, different monitor, taking out the gpu and trying from the motherboard, only 1 stick of ram, every ram slot and still nothing. I sometimes get 4 short beeps then a 1 second pause then another 4 short beeps but that's only when the ram is in a certain configuration. I've had my computer for a few years now and have never recieved this error code. I haven't tried anything with the cpu, or power supply but I have tried clearing cmos and new battery for motherboard. The strange thing is that I don't get no signal when I tell the monitor to search for input from hdmi, only get a black screen. I don't get bios screen or an option to go into the bios or try different boot methods or command. My computer hasn't really had many troubles in the past so I don't know what it could be. I have travelled with it 2 times in the past week to friends houses but was careful with it and it worked at the houses both times. I can't find something suggesting what the beep code could be and have come here as a last resort. Someone please help and thank you in advance
