Troubleshooting Error: NMP: Parity Check Memory Parity Error The System has Halted

We had a PC that would not access the internet at all.  It constantly showed an ethernet connection but DNS lookup would fail if you tried to access a website.  I ran Malwarebytes on there but it didn’t come up with anything and I couldn’t update it so I figured I’d need to get internet access back up so I could run it.  My first hunch was that some kind of malware had altered the internet settings so things were being blocked.  I googled the issue as well and ironically, the overwhelming answer is that it is NOT a memory issue, RAM memory that is, so I didn’t mess with the RAM.

Troubleshooting Error: NMP: Parity Check Memory Parity Error The System has Halted

Equipment:

  • Dell Optiplex GX520 (Small Form Factor)
  • OS: Windows XP, Service Pack 3
  • Broadcom NetXtreme 57xx Gigabit Controller Network Interface Card

Here’s the things I tried:

Step 1: Manually set the TCP/IP settings.

I manually set the IP address of the machine, the DNS servers, gateway, and router addresses.  This didn’t help–no luck.

Step 2: Reinstall the network card drivers.

I tried to uninstall the NIC driver but the device manager application would stop responding whenever I tried to uninstall the drivers–no luck again.

Step 3: Disable the Network Adapter.

I thought that maybe I could uninstall the driver if it was disabled first but the device manager stopped responding every time I tried to disable the network adapter.

Step 4: Format the HD and reinstall Windows XP.

I wiped the drive and reinstalled Windows XP and then when it came time to install the network driver I got one of Microsofts beloved blue screen of death with the error:

Hardware Malfunction NMI: Parity Check / Memory Parity Error when installing the NIC driver

Step 5: Try an previous version of the driver.

Dell allows you to download older versions of drivers so I decided to give that a try.  I got the same result with the same blue screen.

Step 6: Reinstall Windows AGAIN and install the NIC driver.

When I went to install the driver it gave me the blue screen again, rats.  It’s looking like the network card on this motherboard is bad.
