Hello all, I purchased a Dell Inspiron 6400 about a year ago. It had Vista Basic OEM installed on it. The person I purchased the laptop from also gave me the install disk. A few nights ago the system would not boot. I then tried installing a fresh copy of Vista. Everything goes fine until the "completion screen" then the system goes to a black screen and will not boot. My wifi light is on aswell as the power light and I can hear the disk still spinning. I tried this several times and I finally reloaded an old copy of XP. I checked the device manager and downloaded the drivers needed. I then ran the Vista check for XP SP2 and it said everything was good to go. I then tried to preform an update to Vista and the same issue happened. I did load this verson of Vista to my Toshiba laptop some time ago but it had been out of commission since Feb 2009 I finally purchased a power cord (puppies are awesome!) and powered it up a week ago. It sill says 27 days to purchase a product code. Anyway I'm not sure if that has anything to do with it or not. The specs of my Inspiron 6400 are: Intel Core Duo 1.73 Ghz 2.5 GB RAM ATI Mobility Radeon X1300 80 GB SATA SigmaTel HD Audio Not sure what type of MB. After installing XP there were a few items that needed drivers. EX: WLAN CONTROLLER, LAN CONTROLLER, PCI DEVICE, GRAPHICS CONTROLLER and SM BUS. I found all of the drivers at Dell.com and installed them. Hopefully someone can help me get vista back on my Dell. Thank you for any advice or solutions.
