HP 8300 Elite USDT Schematics Required
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 between 1hr and 1 week!!! only green power LED and high fan noise, the only beep codes are if the processor is removed.
The second board worked perfect, did windows updates and now only get CR1 LED on board, no other LEDs, not powering up, no 3.3v, no 5v.
Any help suggestions would be appreciated. Thanks
