I Put together a new system two weeks ago and was having the issues stated in the title and after ruling out hardware and removing software, it seems that 360 is part if not all of the problem. I was mostly getting unexpected shutdowns when the system was sitting idle for anywhere between 20 and 40 minutes. It was consistent. I was also getting this info in windows action center (igfxcuiservice module stopped working) as well as the unexpected shutdown info. After uninstalling 360, I let my pc run for two days straight and have zero problems. Last night I figured it was time to confirm so I logged in and downloaded 360 again and this time I got a BSOD within minutes of logging in to windows and when it rebooted it went almost directly to another BSOD. Had to boot into safe mode to use Norton removal tool and now it's been running for seventeen hours fine again. I've been using 360 on all my machines for years and like it but I'm at a loss at this point where to look. Thanks in advance for any help.
