Machine Model: HP Compaq 8200 Elite Convertible Minitower P/N: XZ805UT#ABA
PCIe x16 Video Card: HP AMD Radeon HD 6570
On board video: Intel HD Graphics 2000(integrated)
Operating System: Windows 7 Professional x64
When I enable the on board video in the BIOS, the machine blue screens with "IRQL LESS OR NOT EQUAL". I have tried changing the primary video device to the on board and the video card itself, no luck. When I disable the on board the blue screen doesn't happen. I checked the drivers for both cards and they are correct. I can boot into safe mode with both cards enabled which makes me think it is a driver issue. I would like to use both on board and the video card so I can use 4 monitors.
