Last night I had well a lot running Lastfm, XSplit, at least 50 tabs of Google Chrome, Skype, TeamSpeak, Was livestreaming, etc. Went to go open Photoshop and my Computer crashed so I rebooted and was having some driver issues. And since Crossfire always gave me driver issues with programs such as C4D which I use for work, I finally disabled it and plugged one of my monitors into my other GPU.
But I got a CPU warning, and the offer to change color scenes to something less CPU heavy. http://prntscr.com/1jzjhv - Not sure why, but my RAM refused to move from 55% and CPU kept jumping from around 55% - ~33% even though everything was running idle. It's not at ~5% though.
