Intermittent Pale Blue Screen

[sirnephilim]

I've successfully installed iDeneb 1.6 Lite 10.5.8 (among others with the same results) and can boot without any graphics drivers with no issues. The second I try any method for using a graphics card (9800GTX, 8800GTX, 6800GT) OSX boots to a pale blue screen that occasionally shows the desktop. I've heard of static blue screens like this, but haven't seen anyone complaining of an intermittent one before.

I've tried the usual run of injectors, manually applying an EFI string by Aqua's guide, using the Universal Installer, etc etc etc. Linux works fine, as does XP, so I doubt the problem is strictly hardware. AFAIK everything works fine except this issue.

My hardware is as follows:
Gigabyte GA-EP45-UD3R Motherboard
EVGA 9800GTX 512MB Video
4GB OCZ 1066 DDR2 RAM
1TB Seagate HD

My suggestion would be is to try a different distribution of OS X. All your hardware is known to work so it must be your installation that is at fault in some way and incompatible with your hardware.

Good luck.

Unfortunately I already have tried iAtkos, IPC, earlier iDenebs...

I'm starting to think there's something wrong with the motherboard. I've used the 8800 card in other systems running OSX without this issue. The board I have is Rev. 1.1, which may have changed something.

Eh, I can still use this system as a Linux testbed, my old Atom based LAMPP server is a bit slow anyway.

Shame there is not an option to set the bios to PCIe or PEG 2 and put the card in a second slot as your board only has 1 xPCIe x16 slot.

Check your other bios settings too to be sure that some setting or other is not stopping QE & CI.

Not even sure the problem is QE or CI, for all I know those are working. What I'm getting is an intermittent blue screen that lasts about 90% of the time, but OSX is working in the background. When the blue screen isn't visible, the desktop shows and everything works perfectly for about half a second.

That's really the kicker here, the thought that it's SO CLOSE to working but not quite.
