Computer slows down when connected to external monitors

Tekst:

I am working on a MacBook Pro that has dual GPUS (Intel Iris & AMD Radeon)

The user uses 2 external monitors.

His computer starts slowing down, the kernel usage gets to 87% and oddly bounces as high as 240 %.  The laptop is a bit warmer than usual but no thermal problems. The user reports that when this problem started that it was about 1 hour or so before the computer slows down; it is now starting to slow down in about 5 minutes.

The user has reset the PRAM and also SMC reset but no change.

Is this a hardware failure?  Thanks
