Hi, I recently built a new computer, but have experienced a problem when trying to turn it on: the PC immediately turns off.
My motherboard comes with a built in power switch (with an LED) that glows when I connect and turn on the PSU,
however, when I click either the built in power button or the one on my case, the computer powers up for a second (The fans activate, and all the LEDs glow) but immediately shuts off.
Pressing the power button again has no affect, but If I hold it down or restart the PSU, I am able to turn the motherboard off and then back on. The problem however, repeats every time I do this. Also, when I connected the computer to a monitor, there's no video output.
I went through stickied checklist and nothing seems to apply to my situation. (I don't have a system speaker though, so I wasn't able to test for beep-codes.
So far I've tried re-inserting the CPU, applying thermal paste reconnecting everything, and testing with only the power supply connected, but nothing seems to be working.
