Computer Build

Can any one help! I know I’m a novice and you’ve all been there and had the T-shirt but I’m just learning, after new build I connected up and fired up the computer but there is nothing on screen, there is beeping sounds and I’ve read they mean somethings not working properly, anyone out there know what it means when there are 1 x long beep and 3 x short-…then-….. 1 x long and 5 x short beeps….Please don’t get to tecnical with me…I’m getting there but it’s tough out there…….Kenn
