been getting these strange ghostly dots and lines appearing at random in a windows 7 install.
they appear at random, and in different amounts. when they dop appear on screen, scrolling can cause them to "artifact" for lack of a better word and spread over the screen.
the laptop in question is a thinkpad t410. it has been sent back to lenovo and had both the motherboard and the panel replaced (even though the lines show up on external monitors as well) it has also had a clean install of windows 7 done, but to no avail.
anybody seen anything like this before, or know how to remedy it?
