AutoCad :: 2012 SP1 - Locking Up On Commands And Deselecting?

I am having an issue that appeared this morning when I woke up and turned my computer on... My AutoCAD 2012 (full) is locking up on certain things:

-When I select something without a command on (free selecting) it selects the items fine, but when I press the ESCAPE button to deselect everything there is a 1-2 second pause and then it deselects everything, instead of it instantly happening as it did for the past, oh I dunno, 10 years.

-If I select the items then type the command, normally it would instantly start that command with the items I had selected. Now, after selection items, when I type the command, it pauses for 1-2 seconds and the runs the command as usual.

-I am trying to edit an AutoCAD table, normally this is as smooth as butter. Now, not only are the same issues mentioned above happening, when I go to edit a cell, the typing has a 1-2 second delay and then starts. Once I start editing one box, it will move to the next cell smoothly. But if I click outside the box to end editing, there is a 1-2 second pause.

Last night, I randomly thought, "Oh, I'll run my McAfee virus scan because I haven't for a long time", literally I don't remember the last time I ran that. I also thought, "Oh, I might as well run the Dell PC Checkup scan", this is a factory program that came on the computer that again, I can not remember the lst time this was ran. Both scans went through Full Scans and found ZERO issues. The PC Checkup found one issue on an external hard drive that I use for BACK UP ONLY, I was not concerned with this because I figured it was either just an issue in the connection or between the 2 softwares. Also I wasn't concerned with it because if it does fail, it's a backup drive only anyway, so I'd just replace it.
