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?

Well its not your screen acting up.. and given that you got that with print screen.. it must be the driver or something.. really odd – ppumkin Jan 23 at 15:12
yeah, i really cant figure it out. especially given a format and clean install, with freshly updated drivers, right from lenovo's website :/ – adam Jan 23 at 15:33
It is a notebook yea?I missed that.. damn.. must be GFX card problem.. I would call Technical up if you still got warranty and get it sorted.. If it is not crashing out, its not going to memory leaks.. so it has to be GPU acting up.. overheating lately ? – ppumkin Jan 23 at 15:35

Don't let lenovo jerk you over. Tell them you want a replacement or they'll keep doing "minor fixes" until your warranty is up. =D – Mechaflash Jan 23 at 16:20

got the laptop back from lenovo, turns out faulty motherboard/graphic combo was the cause. – adam Jan 31 at 4:45

you might want to state what exactly fixed as an answer, rather than having people dig through the comments – Journeyman Geek Jan 31 at 6:43
As @JourneymanGeek said, please clarify your answer (specify what helped). Additionally, please pick your words a bit more carefully (ex. haunting???). – wizlog Jan 31 at 17:52
problem solved by having lenovo replace the motherboard and GPU. the haunting reference was to Aram Kocharyan's comment. – adam Feb 1 at 2:47
