This is a very old PC, It has a 15 inch CRT monitor and no graphics card (inbuilt I think). Since a few months, the monitor has been getting more and more blurry. I can read text all right, almost fine (except for big bold fonts, where the borders of the text appear blurry), and pics are almost fine too. Its just a general blurring of the monitor, the toolbars, text on the titlebars of windows etc.. Also certain icons seem distorted when they were fine before. This has been gradual over around 10 months and gets worse over time... Where does the problem lie ? Is it the monitor or do I need a graphics card ? Or is it the cable from the PC to the monitor ? I'd appreciate help please, its a strain on the eyes.
