This is the first time something like this has happened after building my computer 7-months ago.. I bought Microsoft Flight Simulator, but every time I try to download it from the in-game installer the computer suddenly reboots without warning.. Firt 5 times it happened after about 200MB downloaded, then I updated my BIOS and re-installed all graphics and chipset drivers, ran sfc /scannow, etc. and now it gets to just over 1GB before rebooting, and once it got to 11GB..
In Event Viewer, it gives the following error every time:
A fatal hardware error has occurred.
Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Bus/Interconnect Error
Processor APIC ID: 0
