If you recently bought, built or otherwise acquired your first gaming PC, congratulations. As a former console gamer who returned to PC gaming after a decade's hiatus, I can say that there's never been a better time than now to own one. The brilliant Steam platform, a flourishing indie scene, and the ever-growing capabilities of hardware have ensured that I haven't once glanced over enviously at what my console counterparts are up to... Ok, so there's Bloodborne on the PS4, but I prefer not to linger on that.

Here are 13 things you can do to safely harness the power of your PC, without any upgrades, overheating or explosions.
