High memory usage issue, and task manager fails to display the cause.

[yotmam12]

Task manager says my PC uses 95-100% of its memory, with the process using the most called "system" at only 200MB out of 8GB, if I set it to display how much it's using in percentages, it says 40-60%.

I'm running Windows 10 Home 64bit, on a 4770k with an MSI MPower Max Z87 Board and 8GB out of a 16GB kit of Corsair Vengeance 1600MHz CL10 RAM (I need to RMA the other 8GB, it's broken), CPU overclocked to 4.0GHz, no memory overclock.

I'm wondering whether it's a software or hardware problem, and if it's the former, how can I fix it?

Looks like your board uses a Killer network controller. Have heard that they have been causing memory issues on Windows 10. Getting the updated drivers for it seemed to solve it for most people experiencing that.
