Windows 7 running programs slowly

#1
I'm having a problem I can't seem to find a solution to. All of the Visual C++ based software that I try and run such as Frets on Fire, Ultrastar or Phun all stutter and chew up 50% of the processor time evn when they are idle. I've tried it on both the 32 bit and 64 bit versions and they both have the same problem. These same programs run fine in Vista on the same system?

Anyone have any ideas? I've tried to alter the processor affinity since it's dual-core, but that makes no difference. Neither does compatabilityoptions or running as administrator.

I'm pretty frustrated....
