Buy a soldering iron that is the right size at radio-shack.
Could be cheap, provided you practice, a lot, soldering on old PCB
boards.

Fix your board yourself.

Use GOOD solder 63/37 NOT 60/40.

60/40 is _bad_ solder ?

Yes. It passes through the 'plastic' stage during cooling. Do NOT jiggle or
you get a cold solder joint.
It melts at a higher temperature. Harder to get melted and get good solder
flow.

63/37 is _that_ much better?

Yes. Get a eutectic solder. [melts at the minimum temp for an alloy of
those metals].

Or did you mean
40/60 which _is_ bad solder ?

50/50 is worse than 60/40 and 40/60 is even worse.
[bad and good in relation to electronics usage. If you are a plumber, 50/50
might be better for your work.]

I have 60/40, will that work OK though? This computer is a 733Mhz
processor so it's not modern.

If you're patient with eBay, you can get a Metcal in parts for $100.
Bought 6 so far for at work. After using a Metcal you won't want to
use a Radio Shack soldering tusk.

A GOOD, temperature controlled, soldering iron is, OF COURSE, better than a
cheap iron.

Thanks for the replies to this post.

It still has solder there, do I need to remove it?

I'll post a few semi-viewable pictures.
