High CPU & Ram usage - occasional BSOD

I upgraded to Windows 10 near the beginning, no big issues.

Problem started about a week back. I came home to a BSOD. The computer also hangs and restarts more often now.

Ram usage is extremely high. I have 16GBs but usually only 50% is used, even with 40+ chrome tab and a running game. The ram doesn't seem to clear too - I'd close most running programs and ram usage will still be high. A restart would be required.

Now, even with nothing on, ram usage is almost maxed. As you can see in the attachment, it's windows services that are causing the cpu/ram spikes. Even task manager is using 10% cpu. since when did task manager use 10% cpu.

I've googled and some thought it was an nvidia drive issue. I've installed older drivers but it's still a problem.

Help?

Thanks

there is no new update from creative. I've reinstalled the drivers nonetheless.

also the timestamp is for march 2015, so not sure if this is the same issue?

the problem I'm having now only started about a week ago
