So I was playing a game and suddenly my pc froze, couldn't do anything but switch the power switch. When I try to turn it on again, my pc won't boot/post into bios, just a black screen and my monitor won't get signal. I then replaced my motherboard and power supply to see if my problem would be resolved. I tried almost everything from resetting cmos to unplugging everything and plugging it back in. I think either my ram or my cpu is faulty but I'm not sure. There is no beeps or LED's indicating anything failed. Can anyone help?

Case: NZXT S340have you removed the video card (if present) and RAM. cleaned their contacts and MOBO slots and reseated those components?
if you do have an add-on vid card, and an integrated mobo ONE, try RUNNING without the add-on vid card.
and try only one RAM CHIP at a time.
