I've checked the device manager, there was no hardware marked with a yellow exclamation mark.

This time when I logged in the account I use previously, everything looked OK, the wallpaper and other settings were just as the way I set up before. But I noticed one thing weird which I didn't take serious before. Several minutes after I logged in, one window would be popped up saying that explorer.exe would be closed abnormaly and asking me if I want to send a report to Microsoft. I usually clicked NO and then the task bar at the bottom would disappear for a few seconds and showed up again. But when I am using the other account, such kind of thing never happened to me.

Is there any explanation to this situation?
