I was enjoying a game and all of the sudden my pc shuts off no blue screen, Wont turn back on at all the next day so i order a new psu, Install the new psu and still nothing will power on, at this point im thinking ok maybe the mobo. after 2 days of tinkering i find the mobo will boot until i plug in the gpu or case fans. having either plugged in (i also have a seperate mobo i tested on),. neither mobo boots with case fans or gpu plugged in. Im trying to figure out exactly what caused this and its very beyond my knowledge.
specs are
Asus z370-a
i7-8700k stock clocked
gtx 980ti
16gb corsair vengeance
psu-evga supernova 1000w gold rated.
I appreciate anyone who takes the time to read and reply to this thread, I just want to know where to begin the repairs and what warranty i need to look into
