Recently inherited a Dell Optiplex 780 USFF, Core 2 Duo, 4 GB RAM, integrated video. I found that it wouldn't play Flash video (youtube specifically, but tried another website as well). I tried updating Flash, updating the video driver, then did a complete clean install of Win7 Pro 32 bit, all to no avail. I KNOW this model will play Flash--I've seen it before. Can anyone please give me an idea of what I need to look at?
