Hello , I have a 2060 oc msi , ryzen 5 2600 , 16gb ram @3000 , and a 550 psu of Corsair. Well I left for university and on my temporary home I didn't have space to put my pc. I came back for Christmas and sometimes the screen flickers , but most of the time it shows nothing. I tried both rams , on every single slot , changed my gpu from top to bottom , changed the sides of the pcie and still got nothing. The gpu fans spin on the same speed, that doesn't seem to be the problem. The monitor seems to work just fine. What shall I do?
