Screen has colored vertical lines and a hazy fog overlayed on it.

I was working on a wordpress site and installed a new plugin. after closing the web browser the webpage was burnt onto the screen as a ghost image.  Rebooting did not help.  Later it turned from a ghost image to vertical lines and finally to a fog or haze all across the screen. it is difficult to see on a light background but it is always there.  The haze is uneven and blotchy. The edges and a corner are less affected.  I reloaded all chipset, bios, firmware and graphics drivers..no effect.  The problem is still visible in the bios screen.  Supposedly that tells us that it is not a software problem and that the hardware needs to be inspected/replaced.  Seems odd that the issue is evolving and sometimes reacting to the movement of the cursor.  If it were a hardware issue would it not be a static, unchanging blemish on the screen?  If it is a hardware problem then what sort of problem would cause this? Can I inspect the connections? What else?  I have uploaded some pics to show my screen haze.
