well.
I reapplied everything.
I changed the walloutlet, used another wire to wall outlet, I grounded the mainbaord to the psu casing with single electrical wire

the problem remains.
what is weird is that this night I really succeeded in installing windows and doing everything with that half-inserted 20 pin connector, and during install I rebooted at least 10 times without flaw. now all I get when reinserting the power connector (only when I reinsert it partially, not when I reinsert it totally)is fans of psu that start buzzing or all fans on cpu-psu-southbridge that start buzzing , diskstation going on, but without booting.
when all fans are working however now it does not boot, even when I reset or try the power button again.

damn, if only I had a shop nearby with stock of socket 939 mainboards, I'd just buy a 2nd one and a new ocz psu to go with it, and I'd be at ease, I could still sell it again when the problem is solved :(

remind me never to buy abroad again, if this mobo is all fuxored, sending it back to germany is gonna cost me more than the pricedifference.
:rolleyes:

Sorry to hear that.:(

it's just such a weird thing, it's as if it gets enough power to make fans buzz, but not to power the entire MB...

but how come it worked yesterday?

I have reseated the sytem about a quazillion times now.
borke it down to all its parts, reseated everything looking for possible damage, errors, and so on.
nothing.

what are the numbers under the barcode ?
starts with K0.........

there are multiple stickers with barcodes.
one says : CP0000000554318

other says : 719072010294

last one says : 54g- K0409903072, it's probably this last one?

there are problems with some versions, that's what I heard.

yep, 0409 isn't good, it has problems running at 220 fsb, so maybe even at 200 fsb, don't know.
try lowering your fsb, maybe it helps to get it to boot and update the bios (if you get it to boot in the first place).

in my humble opinion board is borked, try to RMA it
what shop does it come from ?

where did you read this?

I cannot lower the fsb coz it simply DOES NOT Power up.
it doesn't even get to booting, fans spin and nothing else works, vcomes from cyberport, german shop, goddamn ****aroo, sending this back to germany suxx
I'm getting a 2nd one in Belgium first, but which board???

try the Epox in my humble opinion
