Guitar Rig 5 CPU overloading

I have an Acer 5100 laptop that was given to me.  It originally had Vista, I upgraded it to Windows 7, then I upgraded it to Windows 10 recently.  It had originally been 32-bit Vista, then 32-bit W7, then 32-bit W10, but after I initially upgraded to W10, I created a 64-bit USB to do a clean install of Windows 10 64-bit because the specs said the computer was 64-bit capable.  The 64-bit installation was fine. 
 
Sonar X2a downloaded and installed fine, my interface's drivers installed fine.  Guitar Rig 5 installed fine.  Problem is, when I open GR5, it now says the CPU is overloaded, NO MATTER which amp model I'm using.  Even a standard model with no reverb or delay or any other effects, same thing.  Doesn't matter if it's in Sonar as a VST or standalone.  Same thing. 
 
The strange thing, though, is that it worked perfectly fine when I had Windows 7.  I checked my startup programs, only the ones I need for the computer to run.  4 gigs of ram, should be enough.... not doing any crazy mixing.  What the hell happened?

As a point of information for you, I use GR5 day in and day out. I'm on Windows 10 x64 and the latest Sonar Platinum and GR5 runs very well. What  you're seeing isn't universal. Have you tried reinstalling X2a and (strangely enough) your MAudio interface drivers? I've had a boatload of issues get resolved by reinstalling drivers.

Is there's a way to setup Sonar 8.5 producer to get the CPU monitor not to be so high? I'm experiencing some program freeze (Never happended before).
Thanks,
