When starting windows the desktop icons are loaded and appear fine ...... then
they turn white ... and then start one by one get their proper appearance again .
There's nothing to worry about, I have the same thing happen to me occasionally, if I have too many items in the taskbar; the file icons will be fine and then disappear and then load up again all together in a few seconds.
I don't get the problem if I have 6 or less programs on my taskbar at boot.
I experience the same thing and my system is a bit above the norm. In an attempt to locate the reason, I keep trying different settings and the like, but have not found a direct association, yet.
