When ever I'm at a dark screen or sometimes just in my desktop (I just notice it more with darker images) I have little green specs flickering on my screen in a pattern. How can I go about fixing this? I doubt that they are dead pixels because they appear in random locations. Any help would be greatly appreciated.
No, they aren't dead pixels. They wouldn't show on a screenshot anyway.
Software:
Updated drivers recently?
Hardware:
What are your cards temps like?
Tried another cable/input?
Average GPU temperature is 27°C while idle and about 70°C while gaming.
Drivers are ALWAYS up to date.
I'm using a male to male VGA cable with a VGA to DVI-D converter, which plugs into my video card.
I have tried using a DVI-D to HDMI cable but that lead to major display problems with my monitor.
I cannot seem to find a DVI-D to VGA cable anywhere, otherwise I would try using that.
I got in touch with the card manufacturer and they told me that my GPU temps were too cold and that it is probably what is causing the green pixels. Here is a screenshot of our conversation.
Since it will probably be days until I get a response out of them, can someone here recommend a safe overclock speed for my card. I will be happy with something in the 50-60'C range. When I overclock the card, should I overclock the memory as well?
I have a case with 6 fans, (3 intake and 3 exhaust). I have turned the fans down to the lowest speed and also the fan on the 3rd party cooler. I previously had all fans set at the highest speed. I am still at only 40'C when idle, better than 27'C though according to XFX customer support. I have noticed that a lot of the green pixels have disappeared and only very few appear while idle now. I do not notice them at all while gaming now due to my GPU temps climbing up to around the mid 50 range. Turning down the fan speed has seemed to help out a lot.

Mine computer does the same thing after about a week of running 24/7.
I just shut it down and turn the power off at the wall and push the start button to drain what power is left in the computer. Leave for about 5 minutes and restart. All good again.
The first time it happened I thought my brand new card was faulty, even sent it in to be tested. Nothing wrong with it. Tech told me about doing a complete shut down.
For all we know, it might have nothing to do with temperatures - maybe the fan was causing the card to vibrate too much and the mechanical stress was doing weird things to the connectors and the signals traveling through them.
Lowering the fan speed could have relieved the vibration stress.
I know, that's quite a stretch too but personally I'd buy into this rather than the card running too cool.

You are probably right with your philosophy lol. Cold video card sounds crazy to me too but the pixels are gone, so I'm happy.
