Uh oh. Our computer looks like it's stuck in that every 16-bit safe-mode, but it runs fine. I tried to change the resolution, and the computer tells me to restart me computer, so I do. When I open my compy back up again, there's usually and error and then nothing changes. The color stays the same. I'm have the same problem (sort of) with my audio. Music and stuff won't play anymore. Help!
Could be a number of things. What is the OS your running? What is the size of your processor? How much memory?
My first thought is loss of drivers or some software conflict. The worst case it could be some form of malware. For me to say, I need more information.
