Are the hardware virtualization extensions (Intel VT and alike) enabled in the BIOS/EFI/UEFI of your computer? I experienced the following with VirtualBox and other virtualization software that is using hardware virtualization. If the CPU extensions for hardware virtualization are disabled the performance of the VMs becomes really bad. Everything takes ages to load, the performance overall is bad and the CPU and SSD/HDD gets hammered at 100% all the time. Overall this causes the whole host system to become very slow and very unresponsive.
On another point: is your hard drive or SSD in a good state? Perhaps it's so slow that the I/O collapses when the VM starts doing its work. This could be a likely situation if the HDD/SSD is rather slow or in bad health state.
