I built my computer about 4 years ago; everything has been working fine but over the last month or so the display has got 'shaky'. The problem seems to be getting worse. It is like horizontal lines across screen, screen jittery.
I asked a local PC repair shop, they thought it was classic signs of the TFT monitor decaying. I bought a new monitor but problem just the same, if not worse as new monitor is wider screen. Also is very jittery when I can hear hard drive or processor being accessed. Just in case overheating problem I have thoroughly cleaned inside case and components and checked graphics card connection and turned up case fan but still no difference. Is this a sign of graphics card breaking down? Any other ideas.
