Big green squares and screen flicker

[bobospider]

Hello,

So everything worked fine till now when I`ve opened my pc and my screens started going crazy , flasing and on the screens were nothing just random pixel colors but somehow the cursor was ok and after a restart the screens kept flashing but now were only big green squares .
I`ve shutted down my PC and stopped its power source for 5 minutes and power it on again and now it works properly.

Any ideea what was that and if it`s a sign that something its breaking

Those things are called artifacts and that means your GPU is overheating or failing.
Test your GPU with Furmark: http://www.ozone3d.net/benchmarks/fur/
Monitor your GPU temps with HWiNFO when running Furmark: http://www.hwinfo.com/download.php
And report back with the results. If the GPU is not overheating and the artifacts still appear that means your GPU is failing and you need to replace it

Yep, hot card.

This started happening to me recently, it seems that my case fans had stopped spinning. Little bit of investigation, re-connected a wire to my fan controller and they were spinning again.

Could be fans not spinning, clogged intakes if they are behind dirty filters or a dusty GPU cooling solution.

Thank you for the quick response.
I`ve used the 1080p test
Results http://prntscr.com/8j8tna Max temp was 80C
Also I have recorded the flickering https://www.youtube.com/watch?v=K21zUNZrqYM

Seems like the GPU is not overheating.... 80C is a normal temperature for a GPU. Wait now ... if it's happening again you should try another GPU or use the onboard graphics and if those does not show problems than your GPU is failing.

Thanks for the info. Hopefully it does not happen again
