I began having this problem just a few hours ago. My computer screen suddenly became extremely grainy. If I was to describe it, it looked like normal display mixed overlaid with the dead air you get on tvs with no signal. T
After a few minutes, it reverted to normal, and back to grainy again. I'm perplexed.
My GFX card is an ATI Radeon HD 5670
Monitor model is an Acer AL1916W; res at 1440x900, 60 hz refresh rate.
Really need some help guys, hope you can guys can be helpful.
Thanks guys.
