NMI: Parity Check / Memory Parity Check

[GhostDawg]

Hi, after installing the KB957097 Win Server 2003 security update on a HP ProLiant ML150 G6, I got the above mentioned error message. This only happens when I reboot the machine. It boots up fine when I do a shut down and turn it on again. I have Service Pack 2 installed. Can anyone help? I done the re-seat of the memory already.
