My computer which was bought a couple months ago has recently been running slow in some games and I accidentally knocked it during a game and it crashed and I was forced to turn it off at the power button. It turned back on but then my display was turning on but not connecting via hdmi anymore and my keyboard and mouse weren't working either in any of the ports. Please help, what should I do ?
