Few months ago started getting vertical bars and artifacts while gaming. Checked temps and everything seemed fine until the monitor black screened. Reboot worked once or twice than nothing, totally unresponsive. The SSD is less than a year old and so far I have replaced the mobo, psu, and cpu. After replacing the cpu the pc ran for about a week and I was able to game but then the artifacts and vertical lines came back. Now I have a black screen again, several hundred less dollars, and school projects that I cannot access (FML). Could it be RAM? I am getting tired of wasting my money and time, any suggestions on what to try or how to know whats wrong for sure? Really appreciate any help, thanks in advance.

Also the power button needs to be held down for several seconds to turn off the PC which I believe is longer than it took before.
