100% disk usage by "System" process

[xerxerus]

Hey, i would be glad if someone could help me with this issue i have been having for a while. (Windows 10 x64)

My computer was constant on 100% disk usage all the time, caused by "System" process taking about 17MB/s.

After a random while (could be caused because i started up skype) the disk usage went to 0% and instead, my RAM usage went to 80% (from 8 GB ram) with only google chrome and skype running, both together taking about 500MB RAM.

However task manager is telling me my PC is using 6GB RAM. So there is something using RAM thats not listed in task manager.

Can someone point me in the direction of what is wrong with my pc? Someone in chat mentioned to publish a speccy info, here it is http://speccy.piriform.com/results/W5eQmSjXiqrMDOJBIECbBZP

BTW with Chrome every tab you open starts a new running process...just so you know.

For the memory "mismatch" Task Manager shows the "Private Working Set" Memory usage of a Process, Process Explorer by default shows Private Memory Usage.

My understanding is that the difference is largely that Task Manager indicates how much Physical Memory is being used, whereas Process Explorer will show how much memory it has allocated, including memory that is in the pagefile.

So for example right now I have Firefox showing 1.1GB usage in Process Explorer, but about 900MB in Task Manager, because about 100MB was swapped to disk.
