Hi, I've been trying to fix my Dell Inspiron 1440 Vista laptop for almost a month now. Here's a summary of what's been going on: I started having black screens during startup where the system would hang . When this happened, pressing the power button once would switch off the computer (my power buttons are set to 'do nothing' when pressed). Then Windows gave me a Problem/Solution report that my ATI driver needs to be updated. In the process of updating drivers, I messed things up and the driver wouldn't install correctly. So I did a manual OS reinstallation. However, during the driver installs, I realized I'd made a mistake on the correct order of drivers to install, and I was having trouble figuring out which drivers to put in or not - so I managed to do a Factory Restore to get things back to normal. Now after the Factory Restore, again, I start having the black screen during startup and the error message that ATI needs to be updated - I downloaded the correct driver from the Dell website and updated the driver successfully. But I'm *still* getting Black screens and hangups during startup. In the most recent occurrence, the screen was black but I heard the Vista startup melody go off. I should also note that I've run the full Dell Diagnositcs and all the extended tests which took me hours and hours - no errors whatsoever. HELP ! You guys are the experts, please help me out here.
