Hello. Wondering if I can get some help or ideas for getting BT3 on my laptop. Install freezes after a few seconds.

I know this model is not on the supported hardware list, but many other Acers are so I'm hoping I can get it to install on this one.

Here's the h/w specs:
Acer Aspire 4520
AMD Athlon 64 x2 Dual-Core CPU TK-55
NVIDIA GeForce 7000M (384MB shared memory)

Previously a dual-boot Vista 32bit and Ubuntu Feisty

Currently has XP Pro and hoping to make it a dual-boot with BT3 (partitions already set up for BT3 install).

I get a black screen right after choosing the installation type (does the same for all choices), and after pressing the power button, the BT3 install screen shows but does not do anything. It just kinda hangs there. Here's what I can see on that screen:

...and then it just stops and sits there. I only get the info above after hitting the power button.

I've had problems with most flavors of Linux and this laptop. Ubuntu was one of the only flavors I could get to install properly. The other flavors seemed to have an issue with the video card and/or screen. That doesn't seem to be the case here but I'm not sure what's causing it to freeze the install.

It does the same thing with any of the install methods.

Anyone have any ideas of stuff I can try to get this to install?

edit: just to give more details, error exists with CD or USB install. Both have been MD5 confirmed. The issue is the laptop hardware, not the installation medium. I also tried using just 2GB of RAM instead of the 4GB to see if that made a difference and it had no effect.
