No output from computer

[ecoxdragz]

I was using my computer the other day perfectly fine then today when i turned it on the lights on the GPU and the fans work but there's nothing to the monitor (doesnt even say "no signal")
And my keyboard and mouse lights aren't working. Is my power supply busted or is there something else I could do to try fix this? The power supply is at least 3 years old.

Specs ares:
AMD FX8350
GTX970
16gbs ram
MSI 990fxa gaming motherboard
750w power supply
