I recently overhauled my outdated system, starting with a new GPU which dropped into my setup with no issues. After replacing my mobo, CPU and RAM though, it all hit the fan. It started with crashing to desktop out of every game I tried to play, some with error messages, but most without. Errors including Destiny 2 "Broccoli," and Just Cause 3 saying that my GPU was physically removed. I went through multiple graphics driver updates among other small fixes (including reseating my GPU), and the problem has now escalated into my computer crashing and restarting no matter what I'm doing, from gaming to web browsing. Sometimes it takes 5 minutes, sometimes it takes 30.
