Ok, so I have an HP Pavillion zd8000, and when I boot it up, it just has a black screen. It will start up in safe mode fine, and when I hit F8 when it is starting up and choose "VGA mode" it works too. But when I am in VGA mode - if I try to turn up the resolution it black screens again. I tried re-installing the VGA drivers for the mobility radeon X600, but it didn't work. Any ideas? Anyone who can help me fix this is god.

Is the video card listed and selected within the BIOS?
Do you have a different video card that you can test on your system?

any errors in device manager?
if it is recent, a system restore can help you out.
you can also run from a live cd, to determine if it is hardware or not :

The motherboard has a problem and it needs to be replaced. This is the only way.

To be more precise, the problem is in Video chip and this is a common problem with ZD8000-series of Notebook. Video card is not removable on this notebook.

If your notebook is still under warranty, I would recommend to replace it. If not, then you will have to buy another one or use it in "VGA mode".

Well, I tried many many things before I finally figured it out conclusively, but basically nichkin hit it right on the dot. Here is what I did before I finally figured it out.

It worked fine on a fresh installation of windows on a new tech drive until I loaded the video card drivers. Then it screwed up pretty bad. I concluded it was not a software problem. Thanks guys.
