Waking PC from sleep no signal to screens?

My PC has been working as normal but a few times past two weeks when starting it or waking from sleeping it has taken a bit longer than usual for screen to respond.

But today screen just kept going into standby saying it couldnt get a signal and PC was on with all fans spinning etc.

All I did was turn it off and reinstall the DP ports and then it started up as fast as it should normally... Only thing is my lockscreen being a blue windows default one instead of mine for a few seconds before changing.

I'm dreading any catastrophic failures of my PC components, or am I just overreacting?
