ok me and my friend were on our computer when suddenly everything just went crazy. Firefox kept reopening itself until i had 124 windows, the taskbar kept opening and closing, i clicked on the start menu and it kept typing (..)..(..)..(..)..(..).. etc. and then it opened firefox and searched that. I noticed that it kept reopening everything else i opened (norton, my computer).
I downloaded the k lite codec pack from the codec site and plugged the mic into the audio jack. That's all i did before that.
my computer works now but i would like an explanation.
