Windows 7: Dead-Pixel-like Artifacts

Dead-Pixel-like Artifacts

Lately my pc has occasionally started making semi-random green pixels.

These pixels are print-screenable, zoomable and scroll along.

They occur in any application at random. (They do sometimes form a slight pattern.)


Any ideas on what could be causing this?
Any ideas on a possible fix?

I'm worried that it might be an indication of failing / overheating ram or something.

Is your monitor LCD or LED?
I think you have run-of-the-mill dead or stuck pixels. Usually is a monitor problem, I heard some Government thing called the "Dead Pixel Policy" but it only applies to brand new monitors or monitors that are still under warranty with dead pixels. There are some sites that host software/programs to diagnose dead pixels by putting different colored slides on the screen, like this program here:
InjuredPixels 2.1 Download - Freeware - Utilities Category

There are also programs to attempt the fix of stuck pixels. If it's new monitor or still under warranty with dead pixels than you will get a new replacement thanks to the Dead Pixel Policy.

PwnFrnzy. Look at the screenshots. Carefully. Read first my post again.
I thought the same as you at first, but They are definitely some kind of artifact that occur some time before getting to the screen.

I have a dual monitor setup with a crt and lcd monitor. The pixels display on both. They are not set. They appear at random, sometimes with a slight pattern.

Explanation of the screenshots:
00 - Shot of my desktop. Note that the green pixels occur on both the left (crt) and right (lcd) monitors.
01 & 02 & 03- Three successive screenshots of foobar2000 playing music. In these shots, notice
--> how green pixels appear on the spectrogram
--> and then shift to the left along with the spectrogram as the music plays.
04 - (foobar2000 paused between shots 03 and 04) Using Windows Magnifier, I zoomed my desctop to 650%
before taking the screenshot. Thus demonstrating how the pixels are zoomable.

My deductions:
  • Not Dead Pixels
  • Programs can interact with and move around the green pixels.
  • Possibly software-related.
  • Possibly RAM-related.

I doubt that its a power or temp issue though. (Actually I don't even think its really gpu-related but I didn't see any other graphics-related section to start the tread in.)
