every time i turn off my pc and leave it unplugged for a night long, when i wake up and turn it on i get no post & no beep.
i have to tap on the back of my case a little with my hand and give it a little shake so the pc can turn on normally.
this happens whether my GPU is installed or not, and i think it only happens if i leave the pc unplugged for more than 8 hours.
i tried unplugging it for 6 hours and less, pc turned on normally. but if i leave it unplugged more than that it won't, unless i shake the case.
this is also was happening with my old thermaltake 450w PSU and with my new FSP HEXA+ 500w PSU.
any explanation for why that happening?
