Hello everyone! I am a new guy in your forum. I need some help. I've decided to upgrade my video card. I have Dimention 3000, CPU 2.66GHz and Intel Extreme 2 Integrated Graphics. I've bought Nvidia G-Forge FX5500 , 256MB. I thought it would be easy to change it, but I was wrong. 1. I left monitor cable where it was 2. I pulled out old card 3 Put in a new one 4. Downloaded and installed all necessary drivers for the new card 5 Disabled intel graphics controller via device manager 6. Checked out if Primery Video Controller set to auto in Integrated Devices in BIOS 7. Turned off Windows 8.As I started windows again I saw a black screen. So, what was wrong? Or what i've done wrongly?
