answer:If your icons are not showing up, that is because explorer.exe is not running, so you get no icons or start bar. The way you fix this, is by going to the task manager, opening a new task, and selecting explorer.exe to run, and all the icons come back. However, your problem seems to go beyond that. Have you ever formated it, or defragged the hard drive? are you running any anti virus software? Based on how recent this is, since last night, I am guessing you have downloaded something that has infected you some how, or the computer CPU has taken some damage.
