I am getting this EXACT problem and have been tearing my hair out over it for weeks. I'm using a Dell 19 inch LCD about 2 and a half years old now. Suddenly, these green dots appeared. I have tried everything to get rid of them.
- Reinstalled windows
- Reinstalled directX
- Used alternate drivers
- Reinstalled drivers for all multimedia addons
Nothing works! Still those same dots. They get worse over time too - more dots appear and when I move something on screen the dots streak. It is awful.
I have yet to look into:
- New cabling between monitor and video card
- New monitor
- Possible problem with the AGP slot?
If you are having any luck with this, PLEASE let me know, it is awful.
