I have a AMD FX-6100 processor with 12 gigs of ram, 1 Kilowatt power supply, ATI hd 5770 sapphire vapor-x OC, with a asrock 970 EXTREME3 mobo with windows 7 ultimate and a Das Professional. For some odd reason, randomly my computer will start to be incredibly sluggish and my keyboard and mouse will essentially become unresponsive. I can move my mouse around but I cannot click on anything. If I spam crtl+alt+del it won't boot up task. I scanned my computer with malwarebytes and it found nothing. I used ccleaner to fix the registry and it still occurs. Just now, I tried to restart my computer which has worked in the past, and now it won't boot past bios, I get the message "A disk read error as occurred, press ctrl+alt+del to restart" and my keyboard is unresponsive, I spammed numlock and the light doesn't change, it stays on. Is my hard drive dead?
