This crash is usually caused by to malware and the involved randomly named file in your case is yubhcimo.dll as you can see in the modules list of the crash report.
Try to use MSConfig and disable that file to prevent it from getting started.
Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) to see if that allows to locate and remove the file either manually or with a malware scanner.
You will have to search the Windows registry (Ctrl+F) for references to that file and export and remove involved keys to avoid startup issues with missing files or alternatively use a registry cleaner like CCleaner. If you are not comfortable with editing the registry then it is best to skip this step.
