Hardware problem often means driver problem.
When you have Hyper-V installed, you have to be exceptionally careful about what drivers you have installed. I've even seen a Bluetooth driver bluescreen the management OS when Hyper-V was enabled.
This is just the nature of hypervisors. Most drivers are only tested on an OS that's running directly against the hardware. Run them through a hypervisor, and their behavior becomes unpredictable.
Ultimately, Hyper-V is a hypervisor, and it competes against ESX -- not VMWare Workstation. That's why it's best run on workstation-class or server-class hardware. Basically, situations where the hardware vendor might actually keep the drivers up-to-date. On consumer-level hardware, it's a crapshoot.
