  1. I'd guess the monitor. Heat over the life of CRT monitors would usually end their life, sometimes in smoke, sometimes by losing a color and sometimes by just getting blurry. If it was the vid card it would probably return shortly after reseating the adaptor.
  2. you can try 'degauss' option from your monitor's menu. it won't work all the time. or raise the monitor's refresh rate to 75+ hz. the monitor seems very old so you might notice artifacts like this more often.
    if you haven't cleaned the display, try cleaning it.
  3. i dont mind if it dies(i have a spare lcd) ...i just want to make sure its not the gpu?.btw the refresh rate is 85hz.
  4. If you have the spare lcd, trying plugging it in and check if it solves your problem
  5. You need a new monitor.
