Bad RAM ports?

Hi all. I'm trying to fix up my parents old PC. It was running very slow and they were thinking of a RAM upgrade so I opened it up to check what kind of RAM was in there and the mobo model. When I booted it up after, an alert came up that the memory configuration had changed and did I want to save the new settings, so I did. Now it's only registering 2 of the 256mb ram chips. Port 1 & 2 seem to be dead. Is there any way to confirm this?

I ran memtest but it doesn't seem to tell you if ports are dead, it just checked the 512mb that was there. I also ran CPU-Z and port 1 + 2 were greyed out. Is there some method that will tell me absolutely if the ports are gone? Would reseting the BIOS help?

The weird thing is, it seemed to run faster after this happened. I turned the PC on at my parents house to see how bad it was and it was taking minutes to do anything. Now it's not running too badly, but only on half the memory...weird.

Any help would be greatly appreciated. This was only supposed to be a routine cleanup job that's turning into a nightmare! I don't want to tell them to buy 4 512mb chips if the ports are bad.

Motherboard = P4SD. RAM = 4 x 256mb DDR PC3200 CL3. (supposed to be dual channel but only working in slots 3 & 4 as single channel).It's a Pentium 4 running XP professional.
