MS-6330 diagnostic LED error

[Guest]

Archived from groups: alt.comp.periphs.mainboard.msi-microstar (More info?)

I have a failed PC with an MS-6330 mobo. The failure was intermittant,
but now permanent. LEDs (from top) are Green-Red-Red-Red which the
manual shows as "Assign IRQs to PCI devices". I get the start of the
BIOS display on screen for a few seconds then it goes. No kb lights;
can’t pressed DEL to get into BIOS. Tried resetting BIOS, replaced
PSU, replaced all PCI cards, replaced RAM, replaced mouse & kb. Same
error even if no cards or disks present.

Help, please?

Check for leaking Capacitors

Maybe one of them is bulbing or leaking electrolyte (brown on top capacitor)

Thanks Michel

There is no obvious damage, but C171 & C172 (by the AGP socket) have
very slight browning and the top is very slightly convex compared to
other capacitors.

The fault first occurred about a week earlier, but disappeared when I
moved the RAM & network card to a different slot. The fault has now
returned and is permanent. I’ve tried using a PCI graphics card in
place of the AGP but see the same fault. When starting from cold I get
the initial BIOS display page but then it locks up. If I retry without
leaving it powered down for a few minutes then I get no display at
all.

Capacitor problem does seem likely. I’ve never replaced a soldered
component on a mobo, but am willing to give it a try if you think it
may help. It’s either that or a new mobo, I guess!

Thanks once again,
Peter
