helenofthesims Are you asking about tackling the BlueScreens and LiveKernelEvent errors separately? The latter is often fairly straightforward: do a clean uninstall and reinstall of the graphics driver. This is specific to errors related to the graphics driver, and it only helps if the problem is the driver itself, not something else on your system. Here's how to do a clean uninstall and reinstall:

With the BlueScreens, you'd typically need to use a debugger to analyze the crash dumps and hopefully identify the driver(s) involved, then update or reinstall those. But the dumps aren't always informative enough to make the problem clear. You could instead start by running Driver Verifier:

But it doesn't catch all the potential issues.
You're welcome to send me the crash dumps in C:\Windows\Minidump if you'd like me to look over them for you. I can't promise that I'd be able to tell you what's wrong though. If you are interested, copy the files to your desktop, zip them together, upload the .zip file to a third-party filesharing site (Google Drive, Dropbox, etc.), and link it here.
This is why I suggested a clean install of Windows though. As you can see, it's something of an involved process to address the issues separately, if that's even feasible.
