    My friend is a computer teacher and has five computers at home. One of his computers got nuked. A service centre suspected that the motherboard got killed. He then transferred his Lan card from the nuked motherboard to another machine and the new motherboard showed the same symptoms as the motherboard that got nuked before. Could it happen that his lan card killed his motherboard?
    And Can nuked motherboard be repaired ? Please answer, anyone

    It's possible for a damaged LAN card to kill the motherboard. But try removing the LAN card and see if the motherboard can boot up normally.

    ACTUALLY, THE MOTHERBOARD IS TOTALLY KILLED.So it doesnot work if we remove the Lan Card. Can this mother board be repaired?. Please answer.

    Anything is possible. But is it worth repairing? I don't think so.

    You might as well just replace the motherboard.

    That motherboard is no longer available in the market(Intel D845GEBV2). besides I won't interfere in my friend's matter. He just wished to know and hence I reported the problem here....

    Anyway, thanx a lot for the information.....

    Well any motherboard can probably be repaired ,but from an economic and efficiency point of view, it may not be viable. You can currently buy a E2160 dual core and a LGA775 motherboard with HD audio and 2 gig of ram for less than $250 AUD...this board also has integrated 7 series have to ask yourself is it worth fixing...the speed of the new system will blow away any socket 478 P4 rig...Anyway just my 2 cents...

    Actually in India, where we live, computers are very costly according to the economy of our country because every part of the computers has to be imported from foreign countries. Even the upper middle classes think twice before buying a new computer. That's why this problem has arised.
    Besides ,what do you mean by 'the speed of the new system will blow away any socket 478 P4 rig...Anyway just my 2 cents..' ???
    Thanks a lot for your reply.......

    Ahh.. You are from India. Yeah, computers are more expensive over there.

    What Spanner said is true. What he means is you can replace the motherboard and processor with a new and cheap LGA775 motherboard and CPU which will offer you much better performance than the current PC.

    Yeah, in India they are much more costly than in Malayasia, U.S.A or Japan(I know since I stay here). You can buy a dual core 2.8 Ghz processor, a compatible DG31PR motherboard ,1 Gb 800Mhz DDR2 Ram for Rs 10000 (approximately) which is approximately equal to $220. I think it's the lowest configuration of computers available now....

    Keiichi, If you have only blown some Capacitors (basicly power regulators) it would probably be fixable, look at the little black cylinders with a white stripe down one side, if there are any that are leaking or have a sooty deposit on them they could be the problem.

    On the other hand if you have a dead Northbridge or southbridge chip (the large black squares with a lot of pins comming out of them) it is going to be almost impossible to source a replacement part.

    There are also a bunch of other surface mount parts that can fail, but I wouldnt think that they would cause a total system failer.

    If you do have a dead capacitor or surface mount part any good TV or electronics repair person should be able to replace it, if it is one of the chips you MIGHT be able to find a specialist PC repairer who can fix it, but I don't think it would be likely.

    Hope that helps

    For sure!

    Fifty to sixty percent motherboard defects involve power regulation circuits, specially the processor ones, which, fortunatelly, are made of generic components, available for purchase and easy to remove and replace, like eletrolitic capacitors and transistors.
    When I started with computers, back in the Cretaceous period, we use to fix everithing, but nowadays most of the control logic is on the chipset, the north and south bridges. This litlle monsters you can't buy and even if you could, it would take a very expensive equipment to remove this SMD beasts, not to mention the skills.
    Good luck.

    I would have to say that unless you have obvious blown Capacitors, then you really can't do much.

    Though if your board is that old, it could be a bunch of blown Caps.

    Look around for the black or orange striped Caps, and see if any are bulging up, or if any have popped and have oozed some rust color stuff.

    i repaired mine couple time (on blown up capacitors) for five years but i have to say its not worth because it will eventually causes other components damage too and stablility issue which is not repairable. Like other said, best to get a new motherboard, ram and CPU.

    There's not much we can say other than "maybe it could be fixed, maybe not".

    I've ordered replacement capacitors before (ebay) on a hunch that they were the only item stopping a motherboard from working properly. After a couple hours of careful soldering and a lot of swearing, everything worked fine. There might have been other problems but I suppose I got lucky. Could you do this same procedure? "Maybe". Did you LAN card have some kind of perpetual electrical problem. It's possible.
