I bought a new PC from Cyberpower, and it turns on fine, and then a red light comes on in the motherboard and the monitor gets no signal. Everything is plugged in fine, I just cant get signal to monitor. Thanks in advance for help.

Was your PC shipped to you? Did it have the video card mounted in the MB? Mine was shipped with the card separate so I had to mount it to the MB.

If yours was shipped attached then maybe it has come loose. But check to see if opening the case voids warranty coverage (some are snarky that way).

So I suggest checking the mounting of the card, power connections to the card and verify the comm cable between the MB and monitor is correct ie to the card and not the MB port.

Did you connect the monitor cable to the Graphics card or the motherboard video port? You could try the VGA port on the motherboard to ensure the motherboard is fine.

Check the stupid stuff first. It's bit me in the rear more times than I care to admit... really. Soooo...
Check the phisical cables. Make sure if it takes an added power connector that you have connected one.
Check the actual video cables and make sure they are propely connected and show no overly loose connections. (static in monitor when you barely touch it)
Next is on to the bios. (I did not check your board for onboard features)
Make sure your bios video is set to the correct out if it has one. Onboard video is often set up as default and will stop output on some motherboards. So you may have to tell it which you are wanting to use under the bios settings.
Lastly is the monitor. Most modern day LCD or flatpanels often come with a source input feature. Some automatically detect, other have to be set manually.
Lastly, if possible test the vid card in another machine to make sure it's not a dud or didn't give out.
I hope this worked for you.

I just bought almost the same spec computer from the same company and am having the same exact issue you are, I just sent back the video card in hopes its a dud.

My graphics card fried and took out my motherboard as well.

I actually was fortunate enough to RMA both the motherboard and graphics card.

ASRock gave me the same model motherboard as replacement.

XFX gave me a R9-270X-CDFC.

I feel very and lucky to have bought items from these great companies.
