Flickering pixels on the screen in and out of games.

I am guessing that this issue is down to my monitors or a bad HDMI cable, but I am just praying that it has nothing to do with my graphics card.

About six months ago I got myself a new graphics card and a new power supply, this is on my first gaming rig that I bought brand new. I felt like I needed to upgrade the graphics card in my computer as I was only using an AMD Radeon 1GB 6450 (so not the best). But I only had a 480W PSU, so I also upgraded my power supply. Afraid that I would do something wrong I paid for these to be installed. (Mainly so if anything goes wrong you get a twelve month free warranty so I can blame them). But about a month or so after installing the new graphics car and new power supply, I started noticing these flicking pixels on my screen. At first I thought it may have been my monitors so I have tried different refresh rates and different resolutions, but nothing. It still occurred. I didn't think It could be down to the cable connecting my monitors as it happens on both monitors (one running through HDMI as it's a TV and the other running through VGA with a DVI adapter so it can connect to the graphics card. As I have said before I hope this isn't a hardware issue.

I NEED TO STATE THIS HAPPENS ON BOTH MONITORS AND I DIDN'T HAVE THIS PROBLEM WITH MY OLD POWER SUPPLY AND GRAPHICS CARD!

Here are some links to screenshots I could get of the issue:

Download msi afterburn to check the temp of your videocard. Also download any of the 3dmark benchmark programs and run the trial version of it, it will stress you videocard. Getting artifacts (flickering pixels) is a sign of a videocard starting to die.


Did you buy the videocard new or was it used?

Faalin thanks for such a quick reply. To answer your questions yes the graphics card I bought was brand new in an unopened box. I already have MSI afterburner and my graphics card idles around 39-42 and while gaming 47-55 depending on the game. This is with the fans set to 60%. And thanks for the tip I will use one of the 3Dmark benchmark programs and get back to you with answers.

- Thanks Matt
