Now in step 2 to solver this

How do I reinstall the PCI devices. What does the microsoft tutorial mean by that?

Hi Ello,
Welcome to PCHF!,
What they mean is that you should physically remove all the PCI cards (except the Graphics card, if you do not have on board ) then one at a time shut your pc down, install the card, start up your pc and install the drivers for the card. When you get to the card that is causing the problems let us know and we'll see what we can do about it.

That's just putting the card back.

yea its one of the sticks of ram thats the problem. If I put in my 512 meg ram I get this error. If I put back the old ram stick it works fine. So it is my 512 meg ram thing. Also when I put in the 512 meg of ram my computer dosnt even boot. It just sits their on doing nothing.

Then your 512MB ram is faulty.

my bios sees it though...
