I recently purchased computer parts to build a new PC for my Birthday which was on July 5th. It came in yesterday and I'm having really bad issue's with this motherboard. After countless hours of trying to troubleshoot this I could not find the final verdict but only the supporting factors of it.

First off, when I assembled the PC and turned it on for the first time, it ran for a fraction of a second and shut right back off. I was like WTF? So I realized something was going wrong. I ended up taking the PC out of the case and putting it a-top the original motherboard box and assembled it on there with the bare essentials need to run it. PSU, RAM, CPU, GPU just what is needed to get it to show the BIOS at least.

So here's what I came up with, when I have the 8 PIN or 4 PIN or both connected along with the ATX Power Connector, the PC will run for that fraction of a second all lights and fans turn on as well and shuts back off right after that. Keep in mind the Power On, OC & RESET buttons on the Motherboard are Lighten up regardless if the system shut down along with all the fans and other lights. So the PSU shouldn't be a problem since it's drawing power still. It also does not ever reach BIOS, the monitor still shows no signal. I tried two monitors to debunk them, a CRT via VGA/DVI & LED Monitor via HDMI.

Now when I remove the 4 PIN or 8 PIN or Both and keep the ATX Power Connector in, the system Fans & Lights will run continuously without stopping until I manually turn off the PSU while still no sign of a boot to BIOS. And reading the manual says that you need 4 or 8 PIN to be connected in order to boot. This debunks that no matter what power configuration to the board, it will not boot regardless.

I furtherr stripped the board down to No GPU or RAM. My case speaker will not even get to the point of beeping with these uninstalled. I tried 1 RAM Stick, Removing CMOS Battery.
Still same problem with either shutting off almost instantaneously or fans and lights continuously going with both no sign of a boot / bios. So there is something seriously going wrong with when I plug in those 4 & 8 Pin and possibly the whole motherboard in general.

Very dumbfounded by this please help me.
