Why does Big coloured pixels keep appearing?

[MiNuN]

When I print screen and paste it, it looks normal, so I have to take a picture of the display with my phone (sorry for the smudges)

This has been happening a lot lately especially when videos and games open and it would often lead to crashes, any idea why?

I recently had to uninstall GPU driver and reinstall, then this started happening so I did it again but it did not stop.

What you are describing often occurs when a graphics card starts to fail, the incorrect drivers are installed or in the case of integrated graphics faulty RAM memory.

If you leave some more information about your computer system then I'm sure the cause could be narrowed down.

Make & model - [If self built] - Motherboard, Graphics card (if present) & RAM
OS (e.g. Windows 8 64-Bit)

Sounds like the video card is crashing the system with a GPF. This can cause a system crash and a reboot. However because modern video cards have a memory share between system memory and video card VRAM, I'd perform a memtest86 memory test on it just to make sure that its not caused by a memory stick acting up. I am 99% sure its the video card dying, but there is that slim chance that its a bad stick of system memory that shared with the video card is causing it to act up. Memtest86 is a free utility that can be burned to a CD or DVD to be bootable on the system, or if you know how to make a bootable pen drive / thumb drive, then you can go that route with using that.

Also as said prior... what is the system make/model or specs if custom build etc. Also what video card make/model etc.

You sure it's the correct driver ? ?....More info...

[MiNuN]

Sorry what should I do first?

The first 3.5 years it has never done this before in till I had to reinstall drivers.

I self-built this computer, yes it has been crashing my computer a lot lately.

Assuming for the moment that you have the correct drivers (as all you have to do is go to AMD's website and that it's almost idiot proof). What temperatures are you getting on the GPU under load? Have you cleared dust build up out of the graphics card recently?


I have a HD 5770, which caused endless problems (very similar to yours) from day one. Since I applied new thermal grease to the processor I havn't had a days trouble from it. Not that I'm suggesting that you do this just yet. It could just be dust...

[patio]

If it's 3 1/2 years old...it could be the card failing...
Just sayin...

[MiNuN]

I dusted it recently, is there anything else I can check/do to fix this problem? reinstall drivers again =\ ?

[patio]

If you still have the CD from the vid card revert back to the original drivers....see if that helps.
