If the same thing happens on two different monitors, it's the video card. Try one of the monitors on another computer to be absolutely certain that it is not the monitor.
Drivers do not control pixels. You'll need to replace the video card.

You need a NEW VIDEO CARD -- drivers or instructions will not help.
The hardware (the video board inside your computer) is going bad. If your video board is part of the systemboard, then disable on-board video (in the BIOS) and purchase a new video card. Computer hardware does heat up/cool down -- it wears out over time.
