Running Ubuntu 32bit 12.10 on an Intel Core i3-2100 (3.1GHz Quad-Core)

I have no idea how or why, but my system recently started spitting error messages out of Apport-gtk like crazy.

Not sure if a recent update caused this or what, but the system is barely usable.

Additinally, all 4 cores are periodically maxed out at 100%, but if I look under processes, the highest cpu usage listed is for gnome-system-monitor itself at a only 4%.

Most of the pop ups do not even load correctly.

Apport just shows up in the dock, and the pop up is just a tiny square window with no text or controls.

If this were windows, I would think I have a virus.

Everything worked perfectly up until about 2 weeks ago.

The errors I am getting are...

Code:
Blank popup
Code:
System program problem detected
(Do you want to report the problem now?)
Code:
Possible GPU Hang
Did your system recently lock up?
I have been using Ubuntu for a few years, and I have never had any problems like this.

Please, does anyone have a clue whats going on with my system?

Thank you very much for any help.
