random square pixels on screen

[JVC Vacboyz]

I have an r7 260x gpu, all drivers up2date, but sometimes it appears random PIXEL SQUARES on my screen, and I dont know why and how to fix it.
Ive attached some screenshots so you can see my problem, but they're made with my phone because if I use fraps or printscreen, the pixels wont show (which is weird)

Could be driver related, could be the videocard getting too hot or the videocard just dying.

1. I have all the drivers up2date (ive never had this problem untill this week) - ive checked the drivers and they're up2date
2. Ive used aida64 and my gpu is only 52 degrees celsius (in game)
3. how do I test if the card is about to die? (it's only 2 years old)

Not necessarily, the damage could be in the post processing unit of the videocard, in that case it wouldn't show on screenshots but still be caused by the videocard.

If the pixels are not on a screenshot, that usually means it is not the graphics card, but the monitor. Make sure all cables are plugged in correctly, you may plug them out and in again. If that doesn't change anything, try to change the cable if possible to another one / use the monitor with another PC/laptop to test if the monitor is reproducing the problem on another machine too.

I have 2 screens/monitors, I tried with both, and it has same problem on both, and it randomly appears/dissaperas :'(

If its the videocard dying, a replacement is the only way. You could try different drivers though. Latest it not always the best.

so..ive unistalled all my gpu related drivers, and ive installed driver boster, restarted pc and ive opened driver booster which automaticaly downloaded me a ''standard amd gpu driver'' as it said.. and weirdly enough everything works well now, but my fps decreased in all games with arround 15-25 fps
