Click Start and Open Run or Click Search Icon and Go to/Type msconfig (will open System Configuration)
Click "Boot" tab
Click "Advanced options..." button (will open the BOOT Advanced Options)
Uncheck the "Number of processors"
Click OK / Apply
Restart Windows
Check if the Task Manager now reports: "Cores: 4" and "Logical processors: 8"

Are you using Windows 7 ? If so, upgrade to 10 and the issue will resolve itself.

Did you do a clean install of windows when you installed the new processor? Or are you running an existing install? Usually that should not be an issue but I've seen old install fail to properly detect new CPUs correctly and fail like what your are seeing.
