If you use an Nvidia card, please check out: http://wccftech.com/nvidias-latest-game-ready-driver-allegedly-killing-gpus-plagued-issues/
There is also a thread on reddit: https://www.reddit.com/r/nvidia/comments/4crp3j/warning_avoid_36472_march_28_like_the_plague_its/
Apparently the latest drivers are causing issues for many users, and in some cases even bricking their GPUs. Mods, feel free to move this to a more appropriate forum if need be, but I thought that this would get this most attention from the community.
I apologize if this has been posted before, but after looking around I have not seen one.
Edit The Update in question is 364.72 (march 28)
