HELP: Memory Parity Error

[ladyjudy]

Turn on computer or re-boot and I get this message:
Hardware Malfunction
NMI: Parity Check/
Memory Parity Error
***The system has halted***
Husband installed extra memory and now I get this message. I have to un-plug my DLink wait 30 seconds, plug it back in and windows loads.
We removed the extra memory and it still did the same thing. I have a ThinkCenter and am getting no answers from Lenova.

Please someone HELP! Thanks in advance.

Sitting here thinking how the d-link plugged in is connected to this issue.

Well try no d-link plugged in, or if you removed the new memory already and does the same, try removing the battery on the motherboard for a few minutes, then place it back and hope everything works.

Then if it's actually because your ethernet port is bad on the motherboard can deal with that by adding an ethernet pci card or going wireless.

I don't really have much more as for suggestions on this.
