Go into your BIOS and under "Advanced" will be an option that says "System Agent Configuration" and within that area you will an option for "iGPU Initiation" turn this off.OK, ATI drivers are again gone but I don't seem to have the same exact option as the guru thread talks about, on the latest BIOS there is no option to Force UEFI ROM or Force Compatible ROM.
There are two lines relating to ROM:
PCI ROM Priority: Legacy ROM or EFI Compatible ROM (this is currently set to Legacy ROM)
Option ROM Messages: Force BIOS or Keep Current (set to Force BIOS)
Secure Boot on the other hand I cannot find any mention of and googling it makes it sound like a windows 8 feature only?
As for integrated graphics there is indeed no video output on the motherboard itself. In the BIOS there is an option under Graphic Configuration for Primary Display with the options Auto, PCIE or PCI. I have set this to PCIE when the 5830 is installed. Once I put in the 780 and get no signal, then swap the 5830 back in and finally return to the BIOS, this setting is now back to Auto. I wonder if that is part of the problem?
Tried that but by the time I get back into the BIOS after swapping the 5830 back in the option has reset to Auto. I set it to PCIE, save the settings and reset, then power down. Then install the 780 and power up but get no signal. Power down once again and swap in the 5830 and boot up. Once I am back in the BIOS my version of Initiate Graphics Adapter, called Primary Display is back to Auto again. Though the Initiate iGPU setting of Disabled does stick.And make sure the "Initiate Graphics Adapter" is set to PCIE/PCI
Ok so the 8800GT boots to Windows but then drops the signal? Do you by chance have the Lucid software installed for Windows?Found an old 8800GT that has been in a misc hardware box for years and it behaves the same way as the 780 Ti. Machines boots and seems to progress to windows but I get no signal and my motherboard's VGA led stays solid, reporting an issue.
Seems you my be right or that 8800GT is faulty for all I know. It hasn't seen a computer in 4-5 years at least.
My god is that tiny fan loud on the 8800
