 |

8KTA 3 PRO Computer won't start. Tried resetting at J1- jumpers to pins 2
and 3, replace to 1 and two. Hard drive powered but nothing on monitor
(except "Check signal cable".
Please suggest ways to determine if mobo is dead, and I must rebuild, or
some other cause why no POST.
Suggestions will be much appreciated. |

JAD, the capacitors, cylinders projecting up from the board, do not look
damaged.. I have a pci slot for a vid card. Before that, I'll try something
else and report back. Since now that the HDD no longer powers up, I'm
guessing that replacing the agp with a pci card might not effect the desired
POST.
Your observations are excellent and I appreciate the help from you and from
Dave.

The something else (mentioned immediately above) didn't work.
To try to make my previous post somewhat clearer, no power is getting to the
busses; no card would activate.
Part of the something else was that I found I had, unaccountably, stupidly,
changed/rechanged jumpers on j3, not j1, as I'd thought i was doing.
Whatever j3 is, did I make further probs for the puter by that misstep?
Becoming more certain i must to the stores go for components, and rebuild.

Not so fast, Rob. Try this.
Put the jumpers back the way they originally were. Disconnect all drives.
Remove all expansion boards except the video card. Then power it up and see
if you get anything.

Have you checked the definition of the jumpers yet ? To see what changing
that other jumper may have done.
"Updating ESCD" is where the BIOS flash upgrades a segment of the BIOS
chip, with the hardware configuration changes. If the BIOS chip is in
bad shape, maybe it isn't completing the flash upgrade. You could try
reflsahing the BIOS, but if that doesn't work, you could get another
BIOS chip from badflash.com. Assuming the BIOS chip is sitting in a
socket and is removable.
Maybe that other jumper was a write protect or something.

Thanks, JAD. This was after cmos clear and after removing all but video,
then adding pci/ide drive.
I was thinking that cmos battery may be the prob. Epox didn't catch that
possibility. I'll see if I can get it tested (Radio Shack?), and replaced.
