I recently upgraded my 8300's graphics card, and it is causing problems... Original Specs: Dimension 8300 3GHz P4 HT 1mb L2 1.5gb RAM 305w PSU AGP 8X Nvidia GeForce FX5200 (128mb). Vista Ultimate 32bit I upgraded the FX5200 to a 512mb Radeon HD 2600 Pro. I uninstalled the Nvidia drivers, powered down, swapped cards, and then installed the ATI drivers. Now, for some reason, I only see the color BLUE on my screen... in the BIOS, in Vista... everywhere. What did I do wrong? Can I fix it?
