Hey there, my mom encountered a weird problem on her computer that has been occuring for a while now, randomly graphics artifacts will appear on the screen at random places, such as the desktop or on the internet. The only thing i upgraded was the CPU, can this be causing this? Or maybe a faulty driver? I tried to print screen some pics but weirdly the glitches dont appear when i do that, so i just took some pics with my phone instead. Can someone help me?
