Yes, the yellow triangle. After half a day of performing all kinds of tests on software installed, I noticed there was an update for Google Chrome browser, installed that. Then I uninstalled my video drivers and installed the new Geforce Experience beta drivers and the problem has mysteriously gone away. I have no idea which "fix" helped me out, but after reading some web pages, it would seem that the yellow triangle which I could only click to close and couldn't right-click to interact with has gone away entirely. My machine has been running for four hours straight since my driver reinstalls and changing my paging file to Windows 7 managed. I have no idea what repaired what, but it seems to be resolved.
