Computer will not start.  When power cord is plugged in, PC beeps loudly 6 times, pauses 3 times and repeats.  Power button blinks RED 6 times the white 3 times.  Nothing else.  Replaced power supply, problem is still there.

Hi:

 

See the service manual at the link below, chapter 7, starting on page 114 for how to troubleshoot the beep/blink codes.

 

The thing is, I don't see any reference to 6 red blinks.

On the older model HP business desktops such as the 8200 Elite for example, 6 beeps 6 red flashing led meant the on board  video or video card has a problem.

thanks.  I have seen the beep code chart you referred to, and there is nothing for 6 beeps or power button flashes as you point out.  Purchased the machine in Sept 2016, so don't think it would be a pre 2015 build, but its the only thing chart that shows 6 beeps.

Nothing else starts on the machine.  CPU fan does and power supply fan do not even start.  At a loss.

You're very welcome.

 

I'm at a loss too.

 

I guess you are going to have to call HP technical support and see what they say about it, because that troubleshooting code is not supposed to exist.

 

This is the old beep code chart...Appendix A.

Thanks again.  I will be installing a video card later and hope that will solve this.

Anytime.

 

There may be one issue and that is since you can't get into the BIOS, enable legacy mode and disable secure boot, installing a video card that is not supported by HP for the 800 G2 model series may not work.

 

It's like a catch 22!

Yes, I saw that in forums too.  😞 

I am hoping not to have the issue.  If I do, guess its time for a new computer, unless I can find a replacement motherboard.

Purchased the video card and installed it.
No change.  😞
Guess its the motherboard.....

 

Thanks for being a sounding board on this!

You're very welcome.

 

Sorry that installing a video card didn't work.

 

Hopefully you will be able to find a used but tested and working motherboard on eBay.
