So my problem is this - when i start up the pc or sometimes later, but while browsing the internet, i get green dots in black areas of the screen or sometimes the LCD just goes blank and then turns back on again (the button on the lcd still illuminated).
So i took an old crt monitor and connected it to the second port of the 550 TI card. I had an old crt with only the vga cable so i had to use vga to dvi adapter. So when the green dots appeared on the lcd, they did not on the second crt monitor. I tried switching graphics ports with the lcd, but it still had green dots. I bought a new psu, so its not the psu. Was wondering how to test for sure which part is broken - the lcd or the graphics card.
