Having a little trouble with my Graphics Card

Hi there, and thanks for taking the time.

I'm having a little trouble with my custom built PC, and I think it is to do with my AMD Radeon HD7950.

First of all, the problem:



Occasionally, my screen will flicker and display this, mostly when I am Gaming. Sometimes the colours are different, but it is always vertical
stripes just like in the picture.

When this first happened a couple of months ago, I thought it might have something to do with the HDMI being loose, but fiddling with that proved Futile.
I then read something about some high end graphics cards actually needing to heat up to a certain temperature before you can game, but
that didn't make sense as the majority of the time, I could turn the PC on and play games like Skyrim or Metro 2033 immediately without flaw.

Eventually, I had the idea to clean away the dust inside, so I opened it and removed as much as I could get to.
Then the problem seemed to immediately go away, but I think it is just coincidence, as a few hours later, it started again.
As far as I can tell, it isn't overheating either, as I have liquid cooling, and multiple fans in my case.
My computer is only a couple of months old, as I had it build around the beginning of December, so it surely can't be wear and tear so to speak.

I have a warranty for at least a year, so I am not desperate, I'd just prefer not to have to send it away and wait a month for it to get fixed.

CPU: Overclocked Intel Core i7-3770k Quad Core @ 4.60GHz

Power Supply: CORSAIR 650W ENTHUSIAST SERIES TX650 V2-80 PLUS BRONZE

Thanks again for your time.

  1. Start by removing the graphics driver and running a registry sweep to fully remove the driver. Then install the latest 13.1 or 13.2 Catalyst from AMDs website.
  2. I'll Try that, thanks.
  3. Well, I did as you suggested last night, and it seemed to be working. That is until this morning, where it happened again, and this time it caused my PC to blue screen.

    OK so could be your RAM. Download and burn a bootdisk with Memtest on. The instructions are on the site.

    Okay. I'm also going to uninstall the Driver again and run another registry clean, just in case I missed something the first time around.

    You could do that just to be sure. Try a different program though. I like Ccleaners registry cleaner.

  9. Hate to say this, but it might be the overclocking on your computer making it mess up. The sad truth is with overclocking is if you overdo it, the system sometimes can't handle the performance changes.
