I do not perfectly understand the root of the cause so I think it's better to give you guys and idea of how this came to be;

A few days ago, I've started getting crashes from playing WoW, and It wasn't much of an unexpected surprise as the interior of my PC hadn't been cleaned for about two months. However, I feel like it's important to note that while I was getting these crashes (as I've been launching the game a few times before finally cleaning) my framerate was fairly usual (60+ fps, rarely below 50), I didn't get any lag spikes or long loading screens, my fan would get louder until eventually my screen would go black and my gpu would overheat. Since it was late, I decided to start cleaning the next morning.

The next day, I took out my GPU and it was filled with dust, I used a compressed air can to try and blow away as much dust as possible but it didn't really do much of a job, so I decided to use a very small thin screwdriver to delicately loosen the dust from the wedges making little contact if any to the actual gpu, and then delicately taking it out. When a majority of the dirt/dust was removed, I again used the compressed air to remove as much as I could. I Placed the gpu back to the way it was, and eventually turned the PC back on. Turned on WoW, No crashes, the fan considerably quieter than previously however, without adjusting the graphics, I would get below 30 fps, frequently (every second or so) dropping below 10. Loading screens would take minutes. I considered that maybe my gpu is still overheating, but as I checked using OpenHardwareMonitor and msiAfterBurner my GPU hadn't exceeded 75, (75 being max, usually staying around 65-70). Performance was a huge difference, I went from running High Graphics Quality, having steam, discord, and a few tabs open on my browser open for music, youtube, or movies and functioning smoothly to now; barely even running WoW alone on lowest graphics settings.

Anyone know what the issue may be? and if there are any solutions?

What wattage is your psu? Also that is a high temp just for idle on your gpu..

After ending a few background processes through task manager I've brought it down to 42C when idle, Using Microsoft edge jumps to 46-52 range. I don't know if that's normal or not, thought I'd just mention just in case.

AC intput: 100-240V 10-5A, 50-60Hz
DC Output: 750W (+3.3V & +5V=170W Max)
