Gigabyte GA-7DX+

[dood]

Caps are not visibly failed, but are OST's, so they're getting replaced now to prevent future issues.







Cap count?

(4) 3300uf 6.3v
(3) 1200uf 10v
(8) 330uf 25v

I have to ask, why the need for 25v rating?

Re: Gigabyte GA-7DX+

Tested the board before recapping... no post.

Recapped anyway, still no post.

Tried all the culprits, CPU, FSB speed, RAM, Cards, drives/nodrives... simply won't post. Board was a freeby and was not known to be working, so I'm pulling my good caps back off and trashing the rest. Oh, but I will keep that massive NB heatsink

Did you try switching to the backup BIOS?

Re: Gigabyte GA-7DX+

Clear CMOS yet? CPU heatsink fan have power or not when short PWR ON jumper?

Re: Gigabyte GA-7DX+

1. Backup BIOS it supposed to be activated automatically when the main BIOS fails. There's no hard switch that I know of.

2. As such, there's no clear CMOS jumper, either. I did pull the battery (with the PSU off) and short the contacts, but that didn't help any.

3. As soon as I turn the PSU on, the board fires up and sits there humming along. I can then shut it off, but only by shorting the power on spot for 5 seconds. Once it's off, it will stay off, but firing it back up still won't get it to POST.

Re: Gigabyte GA-7DX+

measure vcore.
might be a dead cpu.
see a lot of bad amd .
they are fragile.

Re: Gigabyte GA-7DX+

I've also tried it with two different known good CPUs

an Athy XP 1500+ (133mhz FSB)
an Athy 900mhz (100mhz FSB)

And yes, I did have the FSB jumper set correctly both times

It seems short circults, need to cheap voltage of the compents by a multimeter. Hwoever, that's need many of repair experience. I think you should a little experience at this level, so give up.

LOL, thanks for the vote of confidence, Joe.

Sorry for typing mistake, lol.

cheap = check
Hwoever = However

Nice work on putting that nice Northbridge heatsink on the GA-7VA shown in the other thread!

Actually, both boards came in with those 'sinks on them.
