Hi,
Wmiprvse.exe, also known as Windows Management Instrumentation, is a Windows operating system component that provides management information and control in an enterprise environment. It is stored in the Wbem folder located in the Systems folder and is used to query and set information on desktops, applications, networks and other enterprise components.
You may boot the computer in safe mode and check if the issue persists.
Windows Startup Settings (including safe mode): http://windows.microsoft.com/en-in/windows-8/windows-startup-settings-including-safe-mode
If the issue does not occur in Safe Mode, then perform a clean boot and restart the computer to check the status.
A clean boot helps to verify if any third party application service or startup item is causing this issue.

Keep us posted on the status of the issue and we will be glad to offer our assistance.
