I am doing a "vanilla" installation using the excellent instructions in this installation guide, and have run into a problem:
First, the hardware list:
Motherboard: Asus P5K-V, latest BIOS (version 1002)
CPU: Core 2 Duo E7500 2.93 GHz
RAM: 8 GB
Graphics: PNY GeForce 9800 GT GDDR3 1GB
This computer has been running Snow Leopard stably for quite a while, so I know there are no fundamental problems with the hardware.
When I boot from my prepared USB drive, it boots the operating system to the point where the graphics mode is engaged, and then I am left with a white screen initially with a mouse pointer arrow, and then with the "spinning beachball". Since it takes quite a while to reach this point, I have left the system in this state for a long time to see if it ever recovers, and so far it hasn't. I know that the CPU hasn't crashed completely because the "beachball" continues to spin, I can move the mouse pointer, and the system even blanks the screen if I let it sit long enough, turning it back on when I hit a key on the keyboard.
I have used a variety of boot arguments: -v (I would never boot without this one!) GraphicsEnabler=Yes (graphics come up, but then something else seems to hang), -x (safe mode simply takes longer with the mouse pointer arrow before the spinning ball appears), but nothing seems to give a different result.
Any suggestions? What else might I try? Is there any way to have the system provide additional debug information?
Thanks in advance to all.
