Okay so this all started with the fans on my current GPU crapping out. Not entirely dead, but failing and making a lot of noise. I eventually settled on replacing it with my previous card for the time being while I wait on XFX support, but now I'm facing the issue of it just crashing. I'm not really sure what it is, but the computer will still be on, though both the GPU and CPU fans stop moving which leads me to believe they just stopped, for some reason. It's possible that it's overheating since it only happens while playing games but I have good airflow in my chassis (or at least, as good as I can possibly get it). I haven't caught it at high temperatures because of course Radeon doesn't warn you when your GPU is about to overheat and doesn't even tell you that after it overheats. I also have used this card before and never had any problems with overheating, even using Radeon's terrible default fan settings. I'm worried that somehow the slot was deformed (the new card is a big card, though I do have a brace on it) since this only started happening AFTER I swapped out the GPUs. It took considerable force to actually remove it which seemed unusual. And no, I'm not a moron, I pushed down on the tab thing to unlock it. The slot itself doesn't look deformed, but I'm not really sure what else it might be.
