Read the entire discussion if you must but it took a few tries for them to go get the latest video driver.
In your case you didn't heed the words in red. Why?
A few weeks ago I upgraded my XP computer to Windows 7, and for the most part it's worked flawlessly.
I noticed, though, that the device manager had a yellow exclamation mark under "Video Controller," and it said that it couldn't detect any information. I have a graphics card, though, and most internet videos worked fine, so I was a bit mystified as to what a video controller is. I have had issues with watching online videos in full-screen mode, though. Whenever I try that, they become choppy and black horizontal lines pop up on the screen. Watching files in VLC media player has also made my screen go black a few times, but seconds afterwards it recovers and allows me to watch the video perfectly fine.
Just today, though, I attempted to start up my computer, and when it got to the "Windows Loading" screen, the spiraling Windows logo never showed up. It instead stayed black for a few minutes before I hit the restart button on my computer. This time it brought me to Startup Repair, which I ran two times.
Once those were done, it restarted with the Windows logo, but after sitting there for a moment, it flashed a blue screen for a split second and restarted. Because I couldn't think of anything better to do, I ran a memory diagnostic, and it says everything is fine with that.
Another run of the Startup Repair tool yields only the message that "Startup Repair cannot repair this computer automatically," and the option to send Microsoft information about the problem. When I hit "View Problem details," this is what I get:
Problem Event Name: StartupRepairOffline
Problem Signature 01: 6.1.7600.16385
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: unknown

Problem Signature 06: 3
Problem Signature 07: CorruptRegistry
OS Version: 6.1.7600.2.0.0.256.1

So, do you think this is related to the video controller, or is it a separate problem entirely? Where should I go from here?
