It's always a difficult situation when it comes to replacing a motherboard 
on computer that is a few years old.  As has already been stated, the ideal 
situation is replacing the motherboard with the same make and model, but 
this typically means searching sites like eBay to see what is available. 
You may or may not be able to find a used motherboard or perhaps an old 
stock motherboard in this manner.  Sometimes you can get away with swapping 
out for something that is based on the same chipset and is otherwise very 
similar to what was in there (perhaps that is what your computer shop has 
done), but, again as has been noted, this may lead to problems when it comes 
to reinstalling the operating system, since the recovery disk may be keyed 
to an emachine BIOS.

Unfortunately, given the problems that you are having, it looks like a 
re-install of the software is in the future, but I don't know if you'll be 
able to use the recovery disk that came with the computer, unless you can 
come up with an emachine motherboard.  You might be looking at a purchase of 
a replacement operating system, as well.  At this point, I don't know if 
things are very cost effective, given the cost of a basic new system.

Perhaps you can go back to the folks that did the work and explain that the 
replacement motherboard isn't playing well with your current operating 
system setup.  See if they are willing and have the means to back up your 
data and reinstall the OS, along with the drivers, for this motherboard. 
You'll have to have disks to reinstall all your software beyond the OS, 
though, since they won't be able to back this up.

If they do this for you and things are working satisfactorily, I'd suggest 
using some backup software to make a clone image of your hard drive, since 
this will be the only way to replace it in the future, if you should need 
to.

Subject: What is reasonable to expect after paying to replace mother board?

I suspected something like that. I was hoping that somewhere in all the
IT merger madness that eMachines was bought out by HP and that might
explain this anomaly. Is there any other possibility on that HP flash
screen than they installed an HP board into my eMachines? And if that is the 
case and the
only way to save this is to install HP drivers, is that going to trip up
 other programs and hardware that were used to playing well with
eMachines mother board?

PS For those who did not see the earlier posts, I paid to have motherboard 
replaced on my eMachines D2880 and now the computer and programs are 
crashing a lot which it did not do before.
