Windows 8 display problem with windows 8.1

[kasfig]

I have a problem with laptop (Toshiba Tecra A10) with display of icons in the gmail login and the menu page (please see uploaded files) Skype is also affected and possibly other parts of the windows also:
Some icons are only in black and white : some havent got the logo in the icon and other icons are missing altogether (although if one hovers the cursor over the area of the screen which should contain the icon then the desired result obtains eg clicking the button brings up the requisite link
Please can anyone advise as to solution :
Thank you so much
Ian

See if rebuild your icon cache will help. The tutorial is applicable to Win 8/8.1 as well.

Option One is easiest.
