I am attempting to upgrade a system for a client to Windows 7 and am having odd issues with the display driver. It is an Acer Veriton M410 with ATI x1200 integrated video. I was able to install and get the drivers working but in 3 areas it has issues; when UAC pops up, the lock/task manager menu screen, and when installing updates on shutdown. These screens have single pixel high horizontal white lines randomly placed around the screen. Usually is is possible to read and use the screen but sometimes it is nearly impossible. Hardware checks out and it is a brand new install of Win 7 Pro. Anyone seen this before or have ideas? Happens with both the built in windows driver and the ati driver.
