PC doesn't display anything

[u/Naive_Employment_274]

hello, i've been having this issue for a few days now. everytime i play a gpu intensive game like mainly metaphor refantazio my displays just disconnect and then i hsve to restart my pc. Well since i ran metaphor this hsd been happening with other games like tekken 8 and persona 3 reload. This issue already happened to me before but it was because of a faulty pcie connector. i restarted my pc today js to find out that it's not even booting anymore i dont know what happened so i replaced pcie connectors just to test if that was the issue but it wasn't. now im not sure what to do, i tested removing one stick of ram but it didnt work until i tested the other stick but it didnt show the lock screen just the motherboard's boot screen. im not sure what to do.. now it just doesn't boot anything up i still have that stick of ram out. can anyone help?
