Last wednesday I was playing assassins creed origins, my screen went black showing a nog signal and my fans all went crazy! my keyboard and mouse was still working (caps lock could be put on and off) but nothing on the screen! I rebooted my computer and every time I play games now I get random stuttering at any given moment, mostly when things are loading or if something happens on the screen sometimes the stutter can cause my fps to drop when it shouldn't.
I've reinstalled all drives from scratch, updated bios and all software included windows. I;ve even tried going back to old gpu drivers and old windows drivers, no fix. I've been trying to fix my computer all week now and I am just at a loss, no idea what could be wrong. I've also tried disabling things such as firewllas and other windows and nvidia stuff to do with low power modes. I've also tried games on my ssd instead of hdd and I still get the same random stutter.
one thing to note, I like to game at 4k with high settings, usually i get 30-60 fps which didn't bother me but now that I get stutter it's horrible to game. I've tried gaming at 1080p but eveytime something loads in or something happens i get a stutter.
My temps are all fine.
My system specs: GTX 1080 RYZEN 5 1600 16GB RAM 120SSD 320HDD
these videos show what the stutter looks like. the first video is not mine but identical to what i am experiencing.
