During Windows reset there is no display signal

I'm running Windows 10 Pro on my desktop and I've been experiencing some issues for a while. So I decided to run a full reset and remove everything across my 5 storage units as well. The process seemed to be starting off well initially. I selected the option and it had a small grey window indicating progress. When it a hundred percent the display lost signal.

I can hear my desktop running under a heavy load, so I assume it's removing everything. But I found it strange that I'm getting no video signal. All the tutorials/walkthroughs/screenshots of the process don't have the display signal cutting out.

I've tried swapping the HDMI cable from my GPU to my motherboard, but nothing. I've unplugged all the unnecessary inputs from my PC as well.

So I guess I'm wondering if this is a cause for concern. It's been about 40 minutes.
