After arriving from a trip to Atlanta for two weeks, I booted my computer up to find that my AV was no longer working, as for Itunes. I've managed to fix both by uninstalling and later reinstalling them. But the final of the 3 issues, being the one I couldnt fix, is my keyboard volume dial. This being my exact keyboard/mouse :http://accessories.us.dell.com/sna/products/i_o_devices/productdetail.aspx?c=us&l=en&s=dhs&cs=19&sku=330-1824. Do any of you guys have an idea on what could be done to fix this issue? Help much appreciated, Manny.
