New pc worked fine for about 4 months. Then one day it wouldn’t turn on. Not knowing why I checked all the connections and couldn’t find anything. Tried to turn it on again and it worked. This issue of it randomly not wanting to turn on has continued and I’ve come to figure out that if I turn of the power switch in the back and leave it off for a bit when I come back and turn it on my pc will work again. What could be causing this?
