for me i saw that like 16 gigs of my ram was being completely utilized to 99%. I discovered my issue was using a motherboard with Qualcomm Atheros Killer™ E2200 (

I disabled a bunch of shit but you can just update the drivers to the latest and it should work. I'd recommend looking investigating this as it seems it could be potentially related to your issue.
