Thinkpad R60 - Memory Parity Error

Hi guys,

for the past 5 years my Thinkpad R60 has been totally reliable and I haven't had a single problem with it despite being used heavily pretty much every day.

However now I'm getting a blue screen with the following message:

"*** Hardware Malfunction

Call your hardware vendor for support

NMI: Parity Check / Memory Parity Error

*** The System has Halted ***"

This usually happens when using firefox/word.

After searching the forums I've run memtest for a good 5-6 hours with no errors detected and I've also updated all of the drivers using "System Update" however the problem is still recurring.

Any suggestions or anything similar happen with any other lenovo laptops?

When i bought the laptop in 2006 i had an extra 512MB added, could this be part of the problem?

Any thoughts are much appreciated!

Tech Specs:

Core Duo T2400(1.83GHz), 1GB RAM, 80GB 5400rpm HD, 128MB ATI Radeon X1400

 

I would try;

- Known good RAM, see if you get BSOD
- Reinstalling your OS

 

Lenovo offers a diagnostic utility that can run via bootable CD. You can check the memory with it too.

You could also try a Linux disc to see if that gives you any error messages.
