Question PC stopped working randomly

[Payings123]

Last night I was playing Cold war zombies I was having file trouble but not sure if that has anything to do with it. I always just put my pc to sleep and then go to bed but i did notice that the mobo lights were still on and didn't think much of it. today when I went to turn it on nothing happened just the mobo lights on. so I did the basics try new cord, reseat the ram, run it with the basics replaced the cmos battery not sure what else I can do.
