Good CPU, PSU, RAM, keyboard and graphics card
Phoenix BIOS
POST card tester error 44 - "Initialize BIOS interrupts. Verify video configuration."
The board would occasionally fully POST, but then freeze (with error code 44) after a short time when in BIOS config.
The VRM caps all test good (MCZ and MBZ)
There's normal-looking voltages on all of the big MOSFETS that are on the board.
The VRM MOSFETS are not shorted.
Anyway, i mistakenly thought that there was too low resistance on the high side MOSFETS (12Kohm) but after checking out a similar board schematic saw that that was normal.
But by that time i had removed the three high side MOSFETS, three electrolytics, and the six little SMD decoupling caps that were in parallel.
So i put the MOSFETs, electrolytics, and three of the decoupling caps (lost the other three), and powered it up.
To my surprise, it booted normally, no problem, and didn't freeze when in BIOS, i verified this several times, and all appeared to be working well, and all of the rail voltages that were listed in "health" section looked great, "yay!"...
That was, until i swapped the video card (which i had previously tried, and which didn't work) and the board went back to giving a 44 error (even with the good graphics card).
I washed the board, and sun dried it with the help of compressed air, but sill got error 44, (along with no keyboard led flash, or speaker beep).
i can hear the speaker click when i push the power switch, but the POST sequence probably doesn't get to the point where it will beep, like it did when i removed the RAM or put the RAM in the wrong slot.
The four rail voltage LEDs, and the clock LED, light up on the analyser card
Any suggestions that might help resurrect this board again?
