So my old case didn't have the thing that holds those things that you pull out which can hold graphics cards (i forgot what its called) and the back of it was kinda busted but it worked completely fine. Now, i switched cases and added a psu fan i had, i used the motherboard and cooler inside the new case (it was from one of my older pcs) and just put the processor of the pc i was switching into that motherboard. I then powered it on and it sometimes powers off and doesn't show video (it doesn't have a graphics card, this is off the mobo vga output)
