So I built my PC about a month ago for the first time and everything was working perfectly fine until a few days ago. When I turned it on that day, it was a lot slower than usual, and on certain websites, images would either not show up or show different colored pixels and sometimes only show the coding instead of normally. Then the day after that is when I got the Blue Screen of Death. My computer all of a sudden was being really slow to the point where it froze and then the Blue Screen appeared. The text on the Blue Screen was not readable so I just restarted the computer, but it only showed a black screen, so I decided to delete all the data in my hard drive and reinstall Windows 8.1. But unfortunately, the Windows 8.1 setup isn't able to finish. So I am stuck as to what to do next. What exactly is the problem? And would getting a new motherboard solve this? Thanks in advance.
