Ubuntu Installation :: 9.10 / Can't Get Updates / Getting 'crash Errors'

1 month ago we bought this computer. It has a GS7610 motherboard, AMd Athlon 3000+ with 2 gig ram, Seagate 500Gb HD and that's it.

I installed 9.10 64 bit, and all was flawless. Worked straight away, no troubles at all.

Then it was telling me the HS had bad sectors, so we took it back to the store today, and they said there was no problem. They also said that the vertical fuzzy lines were an OS problem, when we thought it was a monitor problem.

They also said that installing Windows would solve the problems.

Ok, so I went through the motions of trying to install a proper copy of Win7 pro I have here, and that went ok, albeit annoying

So, back to Ubuntu and did a full, clean re-install of 9.10 64 bit from the same CD I originally used that worked perfectly.

All installed, and I am hitting serious troubles.

There is a network connection, and I can ping anywhere with a small packet. Anything bigger, no go. I can bring up google, but no further. I can't bring up Ubuntu.com. I can't get updates, so even if they would correct the problem, it doesn't matter because I can't get them into the box.

It can download some updates, then finds one that it can't swallow and just locks up. I am also getting 'crash errors' that aren't a good thing.

It worked just fine, and now it's not.

I have searched and re-installed for the past 8 hours straight and still nothing.

I have this here box running 8.04 that just keeps ticking flawlessly, so it's not an update issue. I am here, so it's not a network or internet issue. Win7 got the internet just fine (sans sound).

I am almost willing to just accept Win7 without sound because at least it's something more than a non-updatable Ubuntu.

(And FWIW, you name anything that has been already said to fix the problem, I have already tried it at least twice already...)

Just re-installed for maybe the tenth time, and this time, for whatever reason, it is working just the way it was originally, and it even has the static on the screen going flat out, which I would really like to know how to solve...

Even got it dual booting with Win7 without effort.
