Ok I bought a new galaxy geforce 6600gt, and thought i knew how to install it properly but obviously did something wrong because its not working. Here's what i did: - uninstalled old ATI drivers (card i'm replacing is a radeon 9250) - changed bios settings to use the integrated chip - plugged monitor into integrated chip - installed new card - tried to install drivers, wouldn't let me - changed bios to agp instead of integrated - plugged monitor into new card - tried to boot computer, but the monitor wouldn't display anything, justa black screen with the power light flashing I'm not an expert with these things, could someone please advise me as to what i did wrong and how i should go about it properly? I've now put the old ATI card back in and reinstalled its drivers. PS. The card has DVI ports only, and i have a CRT monitor so I'm having to use a DVI to VGA adapter. Could this be the problem maybe?
