I was watching a film using Windows Media Player on my secondary monitor whilst using Unity 3D on my primary monitor. This is something that I often do, however yesterday the video in Media Player went glittery and then the Unity editor also became corrupt with lines everywhere. After about 2 minutes my computer blue screened.

Here are the steps that I have taken so far:

  • Restarted computer, same issue after bootup with just desktop showing
  • Cold boot after being off for a while, same issue
  • Took computer apart (all hardware) ensured that slots were free of dust and re constructed, same issue
  • Ran memory diagnostics which passed

The visual artefacts are moving around my desktop each time a window is redrawn. This browser is flickering like crazy as I type. I have attached a screenshot of the problem. Not all visual artefacts were detected in screenshot, but it looks like some were (hard to tell).enter image description here

It is weird, as I type squares parts of this window reveal the desktop underneath.

Does it do it in safe mode? What kind of video adapter is in question? – Ƭᴇcʜιᴇ007 Jun 23 '12 at 13:32
I've betting on an AMD card. You should download the latest drivers for your graphics card and reinstall them as a start. – Amicable Jun 23 '12 at 13:41
Yep, the issue occurs in safe mode plus I have noticed it across the Windows starting logo. The issue is not noticeable in BIOS though. Yep (though just before they took ATI I believe). I have always been a big fan of ATI cards. It seems as though I am already running the latest drivers, but I have just reinstalled the drivers and the issue is still occurring (after restart). – Lea Hayes Jun 23 '12 at 17:35
My card is an ATI Radeon HD 2900 XT Pro (1GB version). I have just purchased the following to replace my card. I cannot believe that I have had my 2900 since 2007! Time for an upgrade – Lea Hayes Jun 23 '12 at 17:38

Okay, new graphics card works fine!

So I guess the old one just burnt out or something...
