So, I recently had my HDD fail. I figured it failed since I have had it for years and it was the only part of my computer that I didn't buy new. So I got a new one and it was fine for 3 days, but I got a system error with a blue screen and then when my computer attempts to boot it goes to the black screen. The thing is, when it gets there the white line for typing goes crazy on the screen then settles in the bottom left corner. I know it's the HDD since I'm unable to reinstall Windows on it. The same thing happened with my last one. Could my HDD be failing due to overheating? My case fans and other fans broke so I had none of the fans running and my computer wasn't going to sleep either since my power button broke and I didn't want to keep shorting it to get it running. Could this be an overheating problem? I've already replaced my case so all fans are up and running but I just wanted a second opinion. I have a i7-6700k, EVGA 1070, 16gb DDR4, thermal take 650w. And a Gigabyte B150m motherboard.
