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?
If you boot to the CD that you make from the image, you don't need to care about disk reading errors, memtest is not installed in Windows it runs in its own boot environment that doesn't access the HDD.
