Discoloured Icons

Well this one has me beat.
I've a machine in. Working fine with one problem. The icons in the programs menu (some not all) have turned pink.
Now I'm sure it is simple but can I find it? No
the Machine is a 2 Ghz, Epox 8K5A2+, Rage Fury card.
Help much appreciated.

try finding your shelliconcache with find files, delete it and then reboot.

Thanks NooNoo.
I found it could be cured by TweakUI - there is a setting to repair icons.
Appreciate this and the other posts
