I am trying to boot up/Set up a new to me Dell Optiplex 990 SFF but I am getting this screen on my monitor. I have no idea what it says.?

Answer 1

Me neither since you posted no text or picture

Answer 2

No picture?

Either way, please provide more information. I also have a used Dell Optiplex 990, and I've managed to get it working just fine. I'm sure that I can help you.

Answer 3

I have no idea either troll since you didn't include the image....
