One question might be where did you get your install media?
Is your video setup just the laptop screen?
Can you disable onboard devices in the bios, like a camera if it has one?
If it isn't your install media, it might be some driver. Have you tried installing the 32 bit version of Windows 7. Since it is less demanding of drivers, it might work for testing.
Also, you can remove the Install Media during the first reboot. Perhaps that would help.
