Alrighty! Put it to sleep last night and today it won't power on. GPU lights off, fans don't spin, but Mobo light does turn on? USB devices powered.

1 year old build; just need to know if there are any best practices on diagnosing which component it is.
Other devices receiving some power might indicate it's not the PSU? Or am I naive?

But the GPU not lighting up makes me think that it's that.

edit:nvm huge f'ing idiot
totally forgot to just..hit the actual power button instead of flipping the PSU switch over and over again... I use sleep so much i'd forgotten the actual power button...
