I'm not entirely sure what I may have done to cause this, but my computer has been acting up in general for a while(it tends to freeze all the time and i have to restart it manually). So anyway, when I log onto my Windows account, I'm not seeing anything more than my desktop image. My desktop icons are not there, and there is no Windows taskbar or start menu. I've been having to open up any programs using Windows Task Manager.

So, I would be incredibly happy if anyone could offer any help with this situation. Thanks.
