PC is using 16% or more ram on startup. Win 10 64bit pro

So for the last three weeks I've had this annoying issue. Were upon PC start and even after power cycles. My PC is using more ram than usual. I have 16gb of ddr3 2400mhz ram and another 16gb set of ddr3 1866mhz ram (and memtest says the ram is good.) and it does it for both. Before this issue my usual start up ram utilization was 16%, now its averaging 40% to 50% and higher some times just on PC startup. I've done a comparison, in task manager and I can't find the program causing this ram issue.

Mobo drivers are update same with with gfx.
NO virus or malware have been detected.

In event viewer, I did see that I had a a couple of warnings.
Reset to device, \Device\RaidPort1, was issued.(Resolved by adjusting power option)
Windows Hello for Business provisioning will not be launched. (Disabled in group policy)

So how can I isolate what is using all this ram at start up. I have a feeling it's something windows related.

Install CCleaner and see startup list and disable anything unwanted (i.e. you know what it does, and you don't want or need it at startup). The same for services and scheduled tasks.

After hours of troubleshooting, I found that the memory consumption was being done by my antivirus software. I've since uninstalled and got a new one, and ram is back to normal usage.

That motherboard also has a Killer Networking NIC. This is known to cause a memory leak when used with Microsoft's generic WHQL Ethernet driver. Make sure that you have installed the latest drivers from Killer's website.
