Several times over the last couple of months while playing games, my monitors have gone black and no picture has come back on them. This also happened last night while playing vr when my headset went black. After restarting my PC everything started working fine again. I don't know if this is caused by overheating or not. My temps are usually between 75 and 85 Celsius when under load and I have never seen them get any higher than that. However, I am not always monitoring my temps and every time this has happened, I wasn't. If this is overheating, it could be due to what I have noticed to look like my heatsink separating from the top of my GPU. I am not very educated on GPUs so any help would be great.
