Screen Error

[Charles321]

I am having a screen error, where old images are staying on my screen...the images sort of stack on top of each.
I wish i could cut and paste the image to show you...but can anybody explain to me why it is occurring.

FYI: Yes i know if i restart the comp it will go away...tell me what i dont know...what causes it?
I am running:
Intel Q9550;
4gb Ram
OS= 7-64bit Pro

can you take a screen shot and post it.

you can use the print screen button on to copy your desktop to the clipboard. then open paint and save it. might give us a little better incite to your issue. also are you running onboard graphics or dedicated like and ati or nvidia
