Hi guys I'm having an issue with a HP Compaq dc7800 Convertible Minitower PC where it doesn't post or start an install of any windows Vista/7/8 apart from Windows XP. I've also tried to test it with Ubuntu but it crashes aswell. I've pin pointed the issue to be with the NVidia Quadro VS 440 card that's installed in the machine as once removed and using the onboard graphics then all works fine. But I would like to keep the card as the plan would be to use 4 monitors, This is the BSOD that gets generated with the card in.

'The bios in this system is not fully ACPI compliant' I've updated the BIOS for the MOBO in the system to the newest available from HP. I've also gone in a search for the NVidia NVS 440 bios update but no luck with finding any. Any help or tips? I've used Windows XP, Vista & Windows 7 on an array of different DC7800 SFF which I believe share the same motherboard as the mini-tower without issue. We had HP OEM Nvidia NVS 285 or NVS 290 though. See if manually map IRQ addresses helps (Keep SATA, LAN and Video on separate addresses; e.g.

5, 10, 11), save, power off & back on. Some machines would fail on ACPI related issues until this was performed. You might be able to flash the bios to another vendor/OEM on the card but do so at your own risk.
