If the MOBO is old, then it is likely that several of the parts are no longer available new.

 

There are places like ebay, but you tend to find whole mother boards.

 

Your best bet would be to buy a whiole new motherboard second-hand from ebay, it will work out cheaper in the long run, especially as there is no gurantee you won't find you need other components as well.

 

For example:

ive always repaird mother boards that i have had that have gone wrong myself this mother board is the victem of a pwersurge so some of the magor components like the chips and cpu holder are bunt out in the past when one of my mobo's has gone wrong it has ushually been a capaciter or solinoid so i just replace the components and it has always worked out cheaper for me then just replacing the whole mobo i dont whant to buy a second hand mobo to replace this mobo or to get parts of it as that would be more expensive electronics parts are very cheap and so are computer chips but it is finding out were to get them thats the problem ive already estimated that the total amount of money i will probberbly need to spend will be no more then 10 quid so it will be very cheap to do it this way i just need to know were to buy the parts from

You could trye Farnell (http://uk.farnell.com/jsp/home/homepage.jsp) - they have pretty much every electronic bit I've ever needed but not sure whether they'd have things like northbridge controller chips is another matter

 

If it was me then I'd cut my losses and go for a whole new board like Simon suggests

There used to be supplies of Japanese semiconductors for TVs and videos that were sold by RS and Farnell such as Grandata, but I'm not sure if they sell specialist computer chips. You are probably better off replacing the board if it is more than a few years old. My findings are that specialist computer chips are difficult to buy in consignments less than 10,000 and once they are discontinued then the only way to obtain then is recovering them from a computer board.
