I have a HP Pavilion A6437C desktop with a shorted mobo. I would swap it for a good known one if you are able to fix this one. Board is real clean & manf. in 5/08. All capacitors are good with no bulging or leaking. Hard to find one identical to this one.

A concise, practical addendum for anyone chasing a "Napa‑GL8E" replacement or diagnosing a no‑POST Pavilion from this thread.

The Napa‑GL8E is HP’s OEM name for a Foxconn MCP73 series micro‑ATX board (GeForce 7100 / nForce 630i — LGA775, DDR2, two DIMMs, SATA/PATA ports). It was used across many Pavilion/Presario models, so sellers may list the Foxconn MCP73 model, the HP FRU/part number, or simply “Napa‑GL8E.” (pcupgrade.co.uk)

Match the exact HP FRU or MCP73 revision when buying. HP part numbers commonly associated with Napa‑GL8E (examples shown in legacy vendor listings) are what sellers use to guarantee fit and connector/IO layout — searching by those FRUs avoids incompatible revisions. Generic retail boards with the MCP73 chipset can look right on paper but may have different front‑panel headers, I/O shields, or HP‑specific firmware. (the620guy.com)

Minimal diagnostic checklist before replacing the board:

  • Breadboard the board on a nonconductive surface with only CPU, one stick of RAM, and PSU connected.
  • Swap the PSU with a known good unit or measure +12V/+5V/+3.3V on the 24‑pin connector.
  • Clear CMOS (jumper or remove battery for 30+ seconds).
  • Try different RAM sticks/slots and reseat the CPU cooler.
  • Remove all drives, cards, and front‑panel connectors; test for POST beeps or LED codes.
  • Inspect power rails and the area around VRMs and MOSFETs for heat damage or lifted traces.

These are standard "no‑POST" troubleshooting steps that catch many non‑motherboard failures. (draketungsten.org)

If the board truly failed, the safest route is an exact HP OEM board or complete donor system (same FRU/revision). HP BIOS builds and front‑panel wiring are often OEM‑specific, so replacing with a non‑HP retail board can require rewiring or BIOS workarounds. The outcome in this thread — finding an OEM Napa‑GL8E — is the recommended path for long‑term reliability. (h30434.www3.hp.com)

Updating my HP Pavilion D6347C desktop FoxConn mobo.
Found one that's an OEM & has been working fine since then, which i'm typing on now.
Really a great machine even though i'm not too fond of HP produsts anyway. Especially HP laptops. Printer's are ok though.
For your reply "helaw" I have a post response update on my link you should read if your still with us.
Take care!
David
