It is possible to complete POST and even enter the BIOS, but all devices have to be removed and RAM kept to a minimum. If I do get enough time to enter the BIOS, it will freeze after a few seconds. It almost feels like the kind of lockup when something is overheating. I usually get a few seconds more of the board functioning when it is left alone for a bit and then cold-booted.
I have tried:
Clearing/Shorting CMOS/Removing Power/Removing Battery/New Battery.
Reseating the BIOS chip.
All chips onboard feel cool to the touch, if not slightly warm.
Getting into BIOS real fast, loading defaults, saving, and exiting (but I've never been able to get a successful reboot; I have to power off completely for another POST attempt).
Reduced EDO RAM from 256MB (4x32MB) --> 32 (2x16MB).
Swapped Klamath CPUs 233Mhz and 266MHz (Both have functioning fans and heatsinks, which are cool to the touch).
Swapped Klamath CPUs 233Mhz and 266MHz and downclocked them to 133MHz (reduced multiplier).
Swapped in a Deschutes 333MHz (even though I know the BIOS is not at a level for support).
Reduced FSB to 60MHz (CPU@180MHz).
Different video cards (Trident ProVidia 9685, Radeon 7000, and Voodoo3 3000).
Tried Trident ProVidia 9685 in all 5 PCI slots.
Removed all IDE devices, but kept floppy.
Removed all IDE devices, and removed floppy.
Removed all IDE devices, and removed floppy, and removed PS/2 mouse.
Removed all IDE devices, and removed floppy, and removed PS/2 mouse, and removed PS/2 keyboard.
Swapped out 4 different power supplies.
Left machine on for a few hours; powered off and then back on.
Removed CPU fan connection and powered up with only CPU, keyboard, and floppy disk (or hard disk).
I also used a magnifying glass to examine the board. Everything looks pretty good, caps look ok - but my expertise limits my notice to obvious damage.
Does someone have any idea what is or might be going on?
Would a newly flashed BIOS help? I've sent an email to 'biosdepot' on eBay, but I haven't heard back as of yet. Maybe a busy weekend.
