Hi Guys. Sometimes after login im getting yellow colored Desktop, this is not my wallpaper and then after a few seconds my wallpaper loads automatically, i have seen this prblm when we apply higher resolution or high size wallpapers over 1mb, and sometimes some of the tray icons are missing too, Eg: ATI CCC and Rainmeter bt they are actually running in background any idea guys, Windows is fully updated........
What have you chosen as the window colour? Check in personlization in the control panel. Try defragging your hard drive and use a wallpaper which shipped with windows to test.
some times if there is a read error the backdrop goes to a default so yours may be block colours also check your customise notifications by right the time(bottomright)
