I'm working on a friends Acer ZG5 netbook. When I got it, it would turn on but the screen was black. I was able to get the desktop screen to appear after running the BIOS recovery flash, and then updated the BIOS to the most recent version. The problem I'm having now is there is a black border on the right side of the screen and actually a portion of another desktop at the bottom. I have uninstalled the chipset and video drivers and re-installed them multiple times. I ran Intel's driver detection utility and it shows the chipset driver up to date.
I believe this might be something in the OS (Windows XP Home) because I installed another hard drive and installed XP and the display was fine. Safe mode has the same black border. The black border disappears on an external monitor but is still present on the netbook.
