Setting up previously used Win7 machine. Color is missing on some windows. I tried to install a program and I could see the text, but where the check boxes are was white on white (check boxes are there). Another example McAfee Anti-virus screen appears only in black and white, so the the screen from McAfee that shows the devices on the network. Normally it has a colored are with a arrow for clicking on to show other devices not shown. Clicking on the area works but the places where the arrow should show are white. I not sure how to describe this problem in internet searches. This problem makes it difficult to use the computer. Any idea what could be causing this and how to fix it?
