Recent issues with 9.2.1.

I just got a new Dell laptop. It's an I7 with a 4 gig graphic card, 16 gigs of ram and 1 TB of storage. As I was setting it up this weekend, I decided to move to Cap One Pro 9 for Sony. I shoot homes for a living and I loved 8.2. Not sure about 9.21. When shooting the sky, the clouds are not white as they should be, they are a light yellow. I've never had that happen before. Today, I was editing and out of the blue, the program just slowed down like it was on Win 95 and 2 gigs of ram. I had to reboot the laptop. Any Clues?
Best regards, PM
