Desktop icons disapper in windows8 - Windows 8

Hello guys,

If i open my computer for a long time and i don't to operate it, my desktop icons will disappear and only the icons's names remain. In the right bottom corner of my taskbar appears a opaque color, so i have to restart my computer and the color will disappear. I reinstalled my windows8 system and my graphic card is new, and the icon promble doesn't work out.

Who knows what's wrong with my computer? Any suggestion would be appreciate!!!

Hi restart,

Have your computer infected virus? You can scan your system by anti-virus software first.
