Hello David, sorry about your problems. My name is Marco and I will do my best to help you.
A Kernel error can be several things, such as the update which had a problem, a software in your pc which would be corrupted or even a malicious file like a virus or spyware.
Update Windows if there are updates available.
Check in your programs that open with Windows. Right-click on the taskbar and select "Task manager".
Go to the Startup tab and check the software that is enabled to start with Windows.
Test each app by running them to see if they work well.
You can run System File Checker, which will scan your system for missing, corrupt or damaged files and attempt to fix them1. This may repair any system errors that affect your PDF files.
