Hi,

First time I built my gaming PC and I got this, not sure if a problem. So every single time my comp boots, there's 1 short beep and VGA Led on the motherboard turns red for less than a second. My monitor is DVI, and it works fine, everything works fine. Not sure if this is supposed to happen on ASUS mobo.

Appreciate if anyone could reply.

The one short beep is normal, that tells your MB is working.
But the vga led is red, that means the gpu or the pcie slot has problem, assuming all the pcie power cables connected, and the psu is fine.
May try use the onboard iGPU if your cpu has one. Or try the gpu in other pcie slot. If the gpu works fine in other slot, the 1st pcie slot has problem. If the gpu does not work on the 2nd pcie slot, try the gpu in other pc.

Thanks for replying, I tried to re-seat the GPU in the same slot, not sure if I plug it the other slot it will decrease performance?
VGA led and 1 beep are there still.

Sorry I forgot to reply on that. I don't know what that is.
I have Sentey 750W, and MSI 970 GTX

Update: My mobo has 2 VGA Led lights(at least - 1 is near mobo's DVI port, 1 is near GPU ). Yesterday I plugged my monitor into the mobo's DVI port it worked fine but today it didn't so I plugged into my GPU's DVI port. So wherever my monitor cable goes, the VGA Led indicates as PC boots.

Which model? Because you say the pc is fine when you used the onboard iGPU, that tells you either the gpu has problem or the PSU does not have enough power for the GPU. You need at least 500W PSU with 28A on the +12V rail. Check out the PSU spec to see it has the 28Amp on the +12V.
You may test the GPU in other PC like your friend.
