Hello,
A few reasons why a computer crashes after it resumes from sleep mode are driver issues and power settings issues. For us to assist you, we recommend that you download the latest version of your display driver from its manufacturer's website.
If the issue persists, we suggest that you turn off the feature Fast Startup. By doing this, it will ensure you that all the hardware of your PC will start up once you turn on your PC. Here's a link that you can visit for you to see how to do it. From there, you'll see a thread with a similar issue, but it has been answered by one of my colleagues, Kerwin Lee.
Let us know how it goes and if you need further assistance, feel free to post back.
