I think I have a short circuit in one of my PC cases (motherboard/RAM/processor replacement in a HP Pavilion case). Whenever I put in the power cord and turn on the switch (not the power button), it automatically boots up and then shuts off after about 2-3 seconds or just won't turn on if I do it repeatedly.
But everything works normally when I move everything into another case. The HP case doesn't use motherboard standoffs so I just use only the hex-head screws and even if I do put in some, the motherboard doesn't line up with the I/O slot and backplate. And even then it still crashes.
Putting in the original mainboard and power supply makes it crash, same with several different other mainboards. But it did work perfectly once before, before I took it out again.
What could be the problem?
