Turned my PC on today and noticed that it failed to boot, when checking my motherboard error lights I noticed my VGA light is active so its obviously a GPU issue. After re-seating my GPU the error has gone away and it boots normal. Just curious as to what may have caused this and if there is anything I should look into that could be a potential future issue. I have run 3DMark benchmarks to test for any performance issues and there are none, results are the same as normal.
