Black desktop/wallpaper disappears

Happens to me to on occasion

ok tried re-installing and got the same result.

with regards to memory I have 4gb although only 3 is being used(32bit). At boot W7 only uses only 27%... Yeah but the background is not gone actually since if you click the show desktop then the background will show but if a window is opened then it disappears may it be maximized or in window mode.

I am using avast by the way... I will try malwarebytes. Thanks/

Okay, so, I've had the same problem too, with the desktop disappearing, and I discovered two things...

1. I made the icons on the taskbar reappear by expanding the taskbar upwards with my mouse.

2. I fixed the black desktop problem by enabling CrossfireX on my two ATI graphics cards.

I don't know if this helps any, but maybe if you mess around with your screen resolution, or graphics card it will do something.

I just remembered something. First time I had the problem was when I unplugged the monitor cable from the graphics card. When I plugged it back in, my desktop was gone.

Hope this helps some.

Got the same problem once i exited Rise Of Nations. May it has to do with screen resolution changing?

I have the same problem occasionally. It only seems to happen when exiting out of a Valve game (CS, L4D) for me, so maybe it is Steam related? However I simply right-click and hit next desktop background picture and it works fine with no need to log out, so maybe this is unrelated to your problem?

this happened to me after playing warcraft3... it got fixed when i used the vista nvidia 181.20 whql driver instead of the WDDM 1.1.

this can also be foreshadowed when playing warcraft3.. if you dont notice it.. before you get the black screen your warcraft3 seems to move in a little bit slower than it should be but not laggy... then when you exit warcraft3 you get the black wallpaper.

you also sometimes get artifacts on the wallpaper while running the slideshow when exiting COD:WAW.. havent experienced it on other games though.. was persistent on WAW until i changed drivers.
