My computer is running on Radeon HD 4650 1 gig video card connected via DVI to DVI to my Samsung 23 inch LED monitor.
Lately, the display would show white dots on black backgrounds and sometimes whenever I encounter dropdown the selections would go black with white dots.
The worst so far (attached) was when the whole web page turned black with some distorted images.
I'm not that techie so I need your help guys. What seems to be the problem and and how can I fix it?
Looking forward to your answers and thank you in advance.
