Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Power plan?

Upon checking, it seems that there's nothing wrong with your system. It is usual that you have to double-click your mouse before your monitor wakes up.

For the meantime, we suggest changing the power plan by following the steps below:

• Press Windows key + S.
• Type in Power Settings.
• On the pop-up window, choose Additional power settings.
• Select High performance.

After changing the power plan, we suggest that you monitor the changes made and check if that will work for you.

Lost Power, now PC won't boot. Powers on and clicks.

I had tried both of those steps. Neither worked. I have a replacement power supply on order. Should be here on Monday. Thanks for the suggestions.
