Thanks for your advice, I tried rebuilding the icon cache, but I can't be sure if the problem's solved.
In fact, there's no problem in the first 30min I start up the computer, but after 30min or more, some icons
begin to disappear, folder icon, file icon, even icons for (C
but some icons still remain.
It looks like it's taking time to load and display them, but no matter how long I wait, it won't finish loading.
I can't open those files or folders when these problems occurr, and some time after I reboot, they occur again.
I'm still waiting to see if they will occur, hope it will be fine this time
alas, it happens again
