White Screens Since Installing Parallels 7

Since I installed Parallels 7 two days ago, I have gotten a number of brite white screens, which only respond to a shut down. I may be unrelated, but when I start my Windows 7 VM, I get 8 or 9 device connection sounds that I never got before. Here is the spec on my MacBook:
