Ok so, I have a pretty much brand new ASUS 1660 SUPER that I got last December, and I have used it with various motherboards since then, however the motherboard I eventually ended up settling on is the ASUS TUF X570-Plus Wifi, I have not had this issue with any of the other boards I have used this GPU with, but heres what happens. I will boot up the PC, have no problems for a good length of time, several days or even a week, then randomly, any process that is being used will suddenly jump to 100% GPU usage, this means anything, Desktop Window Manager, Firefox, etc, and make my PC beyond slow and very hard to shutdown. Once I do manage to shutdown, and I reboot, no problem again for that same period of time. From what I have seen when googling, this seems to be a Windows related software issue (obviously) that could be caused by something ASUS. Again, I have only had the issue with this motherboard and I am assuming it is stemming from that.
If anyone knows anything else about this, I would really love to fix this issue and not have my PC randomly go extremely slow when doing something important. Any comments or help is appreciated.
