Omen PC 3 long + 3 short beeps and no boot

[jacton1]

Last night, I was using my Omen PC when my power flickered off and back on again. When the PC attempted to boot back up, it instead gave 3 long beeps followed by 3 quick beeps and repeats this a few times before powering off.

Thus far, I have reseated the graphics card and I removed the battery from the mother board for an extended amount of time to reset the BIOS to its defaults by clearing the CMOS.

I'm still running into the same error and unsure of what to try next?

According to the troubleshooting guide at the link below the 3.3 beep code indicates a graphics chip failure.

Does your PC support onboard graphics?

If so, see if it works with the onboard AMD GPU.

If not, try a different graphics card if you have one handy.

Edit: I've now confirmed that my computer does not have onboard graphics. I have a friend with another graphics card that I can use for further troubleshooting.

Thank you for the response. I've tried Googling without any luck, is there an easy way to tell if my cpu supports onboard graphics given that it won't boot up? 

I've tried repeatedly pressing escape or F10 after powering the PC on to get me to the BIOS menu, but it doesn't appear to be doing anything and just goes to the beeping then powers off.

Unfortunately, I do not have another graphics card handy right now, I will try to source one though.

Edit to add: I tried booting the PC without the graphics card plugged in, and received the same error if that is helpful. Also, I don't see any other video outputs from the motherboard (such as an HDMI output).

You're very welcome.

Yes, that would be your only option...to test another graphics card and hope it works.

It has to be a fairly modern graphics card that works with a UEFI BIOS--probably something from around 2014 or newer.

If your friend's graphics card works, you can buy a compatible graphics card for your PC if you don't want the same model.

If it doesn't work, it's possible that the motherboard has probably failed.
