Check your bios has the following settings:
- Virtualization : Enabled
- VT-d : Disabled
- XHCI Hand-Off : Enabled
- Legacy USB Support: Auto/Enabled
- IO SerialPort : Disabled
- Network Stack : Disabled
- XMP Profile : Auto / Profile 1/Enabled
- UEFI Booting set to Enabled and set Priority over Legacy
- Secure Boot : Disabled
- Fast Boot : Disabled
- OS Type: Other OS
- Wake on LAN : Disabled
Dedicated Graphics + Integrated graphics card:
- Integrated Graphics : Enabled
- Graphics: PEG/PCIe Slot 1
- Initial Display Output : PCIe 1 Slot
- DVMT Pre-Allocated : 128M or higher
Your system may not have all these settings, some may have different names, some may be hidden within other settings, CSM and UEFI booting being the ones to spring to mind.
You will also need to make sure your Graphics options are set correctly, i.e. Intel graphics enabled, and PEG or External set as default, so your GTX650 is priority graphics option.
