Your post is confusing. You state that the screen goes black during installation but it works fine in Win7 -- what do you actually mean ?
It's important to understand this because otherwise how can anyone help you on whether it's a driver problem or a hardware fault ?
Try connecting an external monitor. If the image is good, suggests that the laptop's screen is faulty rather than the video circuitry or driver.
However it is possible you have simply set the video up so that the resolution is beyond the capability of the screen.
You state that the image on the laptop is visible at some angles, confirm by shining a torch at the laptop screen. If looks fairly normal by torchlight it may be the screen's illumination.
