Hi

 

I noticed my PC or graphics card have problem with -possibliy vram?-  that cause reboots. I noticed 3 ways to reproduce the bug.

 

 

EDIT: found a third way with ACO

 

1: The first way is while playing battlefield 1 if you increase the resolution scale to 200% in game settings on 1080p (to simulate 4k which exhaust the vram) the pc will restart either immediately or in the next 10 seconds.

 

 

 

2: The second way to reproduce this bug is in CSGO. today I wasn't able to play it because when just the map starts to load the pc reboots immediately, interestingly the fix that worked for me was somehow related to vram settings of CSGO (which made me think it's related to BF1 bug). The fix was to edit the video.txt file in C:\Program Files (x86)\Steam\userdata\207083352\730\local\cfg. by chaning the ("setting.mem_level" "3" to "setting.mem_level" "0") which i believe changes the behavior of the game in the way it manages vram.

wasn't actually able to fix it, it was just a chance. i can't play csgo for some reason, pc reboots once the map starts loading.

 

3: Assassin's creed origins, exactly the same way as battlefield 1, Increase resolution scale setting in the game, wait for 1-10 seconds then the pc will definitely reboot.

 

To make sure it's a vram load/fill-up problem and not a case of GPU overload, I tested with furmark which is way more  intensive on the GPU than these games. no reboots.
