It only started to happen today. Asus AI suite is giving me some warnings about cpu temp went above 70 degC every minute or so. So i opened task manager and arranged processes according to CPU usage, and found out that bitcoin-qt is taking up all the cpu usage. I checked the conf fil and ensured that mining is set to 0, so why is this happening?
if a new block is found, it will use all cores available to process it with results in a high usage for a really short time.
