Moved SSD from Y50-70 to Mac Pro 3,1, misconfigured cpu setup in windows, igfxhandler. Exe running cpu to 100%z

Title says it all.

Should I DDU or reinstall?

If I kill a bunch of random stuff the cpu percentage goes to normal, but I shill otly have 4 cores loaded. But, I have both processors running just fine because all my ram shows up and the north bridge sends a cpu2 temp.

What gives. Lol
