However, when I started up a game, I got horrible performance. I left home and came back hours later and started up my laptop with no issues.
In the middle of installing the update, my computer crashed and I got a blue screen of death with the error message being 'DPC_WATCHDOG_VIOLATION'. Everything was fine until I decided to update to the latest graphics driver, which, in this case was 359.06. I have an Nvidia Geforce GTX 850M card and Windows 8.1 64-bit. So, it seems that certain parts of my PC cannot detect my graphics card.
