Plug and play OS definitely needs to be on. Win7 needs to be able to take over IRQ and DMA settings.
Another hint.
Try disabling all redundant stuff, to minimize conflicts.
A list to turn off:
internal audio
all serial and parallel ports
gameport
hd audio
Firewire (aka IEEE)
Gart error reporting (disabled)
a list to enable or Auto:
LBA mode (Auto)
32bit transfer (Auto)
PIO mode (auto)
DMA mode (Auto)
Block multi sector transfer (auto)
Install only 2gb of ram.
I don't know how big the disk is, but install to partition of 50gb or 60gb, not the whole disk as one big partition.
All these steps together might do the trick.
You might also consider trying another graphics card.
if Win7 install succeeds you can one by one enable the disabled hardware and install the drivers for them.
good luck
