My computer no longer allows me to get to the log on portion of loading so I can&#39;t use my PC anymore.  I think it might have had a virus which now won&#39;t allow me to get onto it.  I can&#39;t find my disc for the computer so I most likely won&#39;t be on CS too often until I find a way to fix it or just replace it.<br /><br />Any ideas of how I could get it to work?
