    so the way i installed my graphics switching was that i installed the intel graphics card then the acer ati driver, then switched the bios to discrete mode and installed the amd catalyst driver then switched back to switchable graphics...the problem im having is if i shutdown the computer with the gpu in power saver mode (intel chipset active) it freezes on shutdown and i get a BSOD. if i switch to the ati chip then shutdown its fine...why is this happening?

    the dump says the problem is the usbhub.sys but i think thats just a generic explaination.

    also, it seems that i get better fps with my intel card than my ati card....gpu-z says that the ati cards core is running at 100 mhz!?
