I have laptop Sky X9E2 (i7-6700, 1080Geforce, 64GB RAM, SSD) and Windows 10 PRO, my laptop just stops responding and freezes the screen for 30 sec and then changing colour to random (pink, yellow, red) and then just stays like this for hours until I hard reset it. It mostly happens when I work in the material editor, but sometimes after freezing I restart and run UE again, and it freezes in the first 15 sec, I don’t know why, I can’t even track anything, I restarted my PC yesterday with fresh hard drive, and today it occurred again. The only suspicious thing that left is a RAM. I have 64GB 3000Ghz speed on ram, it very fast in comparison to 2400 that was there by default. I changed my BIOS settings in summer. I had a couple of freezes there, but then I swap them in order and it was working fine. But this is maybe the problem. I had not tested it yet if it’s going to happen again I going to lower the speed to 2400 back as it was by manufacture when I got my laptop. It’s okay, but compare to 3000 for some reason I have noticed significant speed overall in the system, everything just flies. Did you touch any RAM or BIOS clocks?
