Hi,

 

This sounds like a BIOS problem.

 

Try all steps at this site (Link).

 

You may have to contact HP Support (Link) if you cannot recover the BIOS.

 

Regards

Hi,

 

Thanks for the additional information.

 

A 3.4 BIOS error code is a hardware problem.

 

This HP site (Link) lists remediation steps. 

 

The following info for a 3.4 BIOS error is from the above link:

 

Hardware
3.4
The system board displays a power failure (crowbar).*
Indicates potential power system failure.
  1. Reduce to minimum config (CPU, System board, PSU, 1 DIMM of memory) and isolate failed component.
  2. Reduce further if issue persists.
  3. Test known good PSU.
  4. Replace affected component.
  5. If unable to confirm source, replace CPU, System Board, PSU.

Hi,

 

You have some type of hardware problem. 

 

The following thoughts work with a Desktop PC. You have a AIO PC. AIO PCs have most components integrated in the motherboard. This means you may have to replace the motherboard. A cost/benefit analysis may preclude replacing the motherboard.

 

The link in previous response suggests you have to isolate the bad component by only running the hardware required to allow the PC to POST. This means you must disconnect all SATA devices (HDDs and the DVD drive), the front or top USB card reader, and any other unnecessary peripheral devices connected to the PC. Remove any add in PCIe cards you may have installed if this is relevant. Trying a different power supply is also a good thing to do.

 

You should also remove all memory modules. Then test one memory module in each available memory slot. Try one memory module in each memory slot. Start the PC to see if it will boot using one stick of RAM.

 

Try a different known good memory module in each memory slot. The problem can be reduced to a bad motherboard or a bad CPU if the symptom persists after doing the above steps.

 

Have a local PC tech troubleshoot the problem if you don't want to do the heavy lifting and you don't have a HP warranty.

 

Or contact HP Support for factory service (Link) if in warranty.

 

Regards
