Ok, I made it, kind of.

I got it running and yes I didn't have to reinstall Windows, the fix with unistalling some drivers worked just fine.

I have also now installed SETI/BOINC but it only runs one process. Xaak said it would automatically run 2

but it doesn't, but in "processes" it says it uses 100% of the CPU power.

It look like this:

I haven't updated to the chicken version yet, you think that would help ?

Also sorry to be such a bother, but this is all for the team anyway !

They are and have always been set to max 2.

paul wrote No bother at all. Really. Something just toggled in this head full of obscure datum, was that W2K and perhaps XP also sets SMP on the OS install. It can't be set by switching motherboards, it's done on the initial install. I'd suggest some googling on the subject, please don't do a repair install yet, though. There may be a fix for this.

Sounds like you may have it, paul!

The install does a lot of hardware eval before putting software on there.

I would think that checking device manager would tell what Windows thinks it's got for a cpu.

Personally, I wouldn't hesitate about a repair install over the old install.  Just use the same directory; using a new directory will leave you trying to combine things that Windows wants to keep separate...BTDT.

It doesn't say anything there...

It looks like this..

I'll do what ever you think I should, I'm useless at these things.

I suppose I could do a new install of Windows on another hard drive,

I have loads of space !

How ever it's 4.12 AM here now and I need to get some shut-eye !

But I'll check in first thing tomorrow and see what suggestions you have !

It had some problems recognizing the RAM also,

it said it was DDR333 but it is not, I had to change that manually in the bios.

Also it didn't find the other RAM stick at all, but now it have !

Hope your brain is better.

I echo the advice to do a repair install. Windows will install the correct drivers, and you will keep all of your settings, including email and all of your installed programs.

I knew it wouldn't work, but not for the reason I thought.

When I tried it all of a sudden said

"setup has determine that drive C is corrupt and cannot be repaired"

So I will try with a clean install from another drive !

Cool looks like you've got it straightened out, one thing, "your computers" shows 2 E6400's

so you will have to merge those boxes.     Nice addition to the team!
