AutoCAD 2010 :: Search Box Isn't Working

I've got problems using Acad 2012, i'm sure it isn't a hardware problem since the specs are HIGH

First Problem is, when mouse over an icon/box/whatever you call it (eg. Line tool, Circle tool, etc), it only displays the text, but it doesn't show a blue highlight like it's supposed to do, and when i select it, the Blue highlight does not transfer to it, it remains on the Line tool

Second, The Search box isn't working

Third, when i switch from Drafting & Annotation to something else or vice versa, the tabs remain the same, and is usually accompanied by some annoying lags.
