Well I really don't know if this is a windows problem or a hardware problem. I'm guessing it's something with the windows. forgive me if I'm wrong; Well today I was playing the sims like I usually do. But today when I quit the game, the icons on my desktop where all gone. I thought it was nothing and if I restarted it would go back to normal. It didn't. it shows only a few icons, My computer,Firefox,My documents icons don't show. it just shows that icon like when you have some file but lacks the program to run it you know? and the same show on My computer, my folders and everything else. Plus the pc is crashing everytime I get a link on msn, and I had to uninstall firofox cause it was crashing on everysite just as the windows media player crashing all the time. I don't think The sims can do that right? Can anyone help me? I'm really lost here

Thanks in advance
