Thanks but ive tried that.

They've many bios beep codes in hp since their use ami bios and their own bios: own HP bios for 4 beeps: flashing failed; AMIBIOS: Fatal errors on critical components

 

I think in amibios when there was 4 beeps it was the mb...

Im thinking of calling in their warranty, i have 23 of gthese things and EVERY one of them has the same issue.  Damn HP, making me earn my paycheck

Since you have 5... is there any chance that you have one more that works where you could steal the power supply from it to test with?

 

You could also try flip flopping ram sticks around a bit.

 

Were they working at one point, or purchased used and broken?

If you have no idea, why the hell did you post? Did you somehow think posting that you don't know would help? Because it honestly doesn't.

5 beeps (amibios) means CPU error and in HP BIOS means Bios recovered successfuly

since I'd a HP mb with a recovery jumper, i'd look for that

 

I usually start off diagnostics with power supply and RAM, because codes aside... those two are the problem at least 50% of the time. Maybe the DC/DC converter isn't outputting the right voltage for one of the legs and the CPU is throwing the error because of the voltage it is getting.

The company I work for buys the stock from stores that close or go through a disaster.  These came from an insurance company that was trying to slim their margin down.  If you watch the video or look at the picture you will see that everything is integrated.  So their isn't a PSU i can test other than the power brick (which ive tested multiple from diffrent companies and diffrent comps)

The funny thing is,  every single computer is still in their manufacturor warranty.

Yeah, the power brick is what I was talking about, it will likely provide 12v or 19v, then inside of the computer there will be a DC to DC converter that will step it down to 12v/5v/3.3v. I'd start with measuring all of those voltages, a sata plug will have all of them, but since it looks like HP is taking care of you I wouldn't worry about it.

 

HP will just replace a few major components at a time until the issue is fixed, sounds like they are starting with the motherboard... it will pretty much end up with you have a 23 brand new computers when all is said an done. I had a bad front audio jack on one of mine and they replaced the front daughterboard, motherboard, and CPU all at once so that they would be sure to fix the issue lol.

 

Buying pre-builts may seem expensive for what you are getting, but the second there is something wrong it makes up for a lot of it, especially with HP, I've had nothing but amazing service from them.

I've got 350 of the slim version at work and they work like a charm. I remember the dell optiplex gx270 from the old days.... that was a piece of garbage

Where do you work,  HP tech was suppose to come out today but he was a no-show.  Calling HP in an hour or so to follow up on the status
