Hi to all...
Just wanted to chime in on this. First off, you can exchange motherboards with emachines..just watch the standoff's on the case so you don't end up having one hit the motherboard where it doesn't have a hole, it won't post that way, and can easily burn up the board if that standoff hits the wrong spot.
As far as that ghost partition, it's really a symantec ghosted image of the original installation. It will crap-out even if you use the same board if the hard drive that's used isn't at least as big as factory, because they use a drive image in the restore so it looks at the full drive size...so if you had a 40gig drive in originally and put a 20gig in and do the store, it'll go most of the way and look good, till the "ghosterr.txt" is displayed. If they would have used a partition image instead like the new "PC Angel" restore that they use now...you could install it on just about any hard drive over 6gigs.
But what I would do is look on craigs list to see if you can get a replacement board that'a'way...
I think E-Machines are pretty bad-***...the problem is, overheating in the usb part of the board. As long as you keep those things cool ala put case fans in!!!! those things are pretty fast and solid, easily lasting 2 or 3 years. And keep away from AMD's in your emachines....
I'll probably get flamed but, I have a crapload of dead AMD's in my shop, probably 8 for every dead Intel. There's a reason AMD's are cheaper folks...and another reason why they aren't in alot of business offices.
Anyways, that's my 2 cents, love me or hate me, I love you all.
