Hi all, I have just started doing board repair and would like to get a better understanding as to how to diagnose a couple of systems that are faulty.

I have two HP 8300 Elitedesk USDT computers both with different faults, does anyone know where I can find schematics for the following motherboard:-

HP PN: 711787-001 PCTCB0K0Z5C9PQ REV 0K

Bar code on board: 12472358-0000688-69M10AK70B17 K01_0290

Both boards are Intel i5 LGA Q77, one will power on, POST and boot to windows, run for approx 1 day then will not power on again for anywhere...

Hi everyone,

My name is Steve and I have joined this forum to learn more about component level board repair and like the challenge of fixing things rather than just chucking them away.
