High RAM usage - don't know why

post a resource monitor screenshot of ram usage. like stated above

You're running Chrome which will hog RAM resources. The CCC (Catalyst Control Center) is a very big hog as well and not really needed, you can use w7 tools for display adjustments.
Your system has been up for more than 12 hours in the snip, reboot and see what you get.

Type msconfig in the start search and tap enter. In the Startup tab, uncheck everything except your Anit Virus and firewall, reboot and test.

Good catches, Gary. I strongly agree with all.

Servilo Service is also suspect. Never install streaming software which is really spyware in disguise, and can be as pernicious as porn players. Anything that's legit should play in the browser, on Windows Media Player or VLC open-source player. This is an example of sneakware that gets in during torrenting which can also lace files with malware and spyware.

So I would run not only a full Malwarebytes scan but also full SUPERAntiSpyware
scan to root out any of this crap lodged in registry. Check your browser for add-ons allowing none but Flash and Reader. I do not use Chrome because it's pernicious spyware and too heavy on resources. Firefox is the opposite.

If it doesn't settle down after everything but AV is unchecked in msconfig>Startup and >Services (after Hiding All MS Services) then I'd swap out Avast for MSE to see the difference. Avast has bloated up to where it is no longer co-recommended here with MSE.

One thing i would try if you can is to up the amount of ram in your system as doing that will help quite a bit. Also completely exit and stop all processes for utorrent as that is showing up as using the biggest amount of ram.
