The BIOS was 6 months out of date so this is fair enough. I would still like to raise a concern that screen share is still making the CPU hit 85C at occasions which is uncommon for this system, even when running benchmarks and games. Screen Share is crashing Windows. Whenever I run Screen Share (anytime during) in GoToMeeting the computer crashes and restarts very quickly. The processor is hitting 85C+ when running only GoToMeeting and Screen Sharing, which does not seem sensible. The machine can run stress tests like FurMark and Cinebench without crashing so this cannot be due to the hardware overheating from extensive work. Event Viewer provides a WHEA error just before the crash happens. Please see below for the error: A fatal hardware error has occurred.
