It's been three days that I've trying to solve this problem, and right now I have no idea what to do next.
I noticed that my memory usage would get very high as time went on. Windows would use 3GB by itself, with no processes accounting for this. This also caused a bluescreen at one point with a "Kernal inpage error". I've checked in process explorer and the All Users section of task manager, but the RAM usage amounts don't add to the total usage. All of this memory is in my Nonpaged pool, and after further searching I've found that it increases whenever a program is downloading something from the internet. I've updated my Ethernet port's drivers but that has had no effect whatsoever.
I've tried tdsskiller, combofix, and ran a scan with Avast and Malwarebytes. All of which have found no problems.
Any help would be greatly appreciated, it's annoying to have to reboot my PC every 2 hours if I have a download running...
