Gina does not like more than sixteen processors.
So be sure to start Gina.exe via the command line with the start command and specify the number of processors.
c:\windows\system32\cmd.exe /C start /affinity 16 <path>/GINA.exe
the path is obviously where gina exist on your computer. Once you get it loaded, go to performance tab and limit it to 16 cores and your problems are solved.
