NMI: Parity Check/ Memory Parity Error -- System crash

[a-mac]

Just so you guys all know that this is NOT a Dell-specific problem. I have a netbook - Samsung NC10 which has been operating just fine since I got it last October.

This morning I booted up and found my wireless internet not working (problem with router not netbook) so I used a plug in USB modem instead. Midway through connecting up with the modem, I got the that this thread is all about -

Hardware Malfunction
NMI: Parity Check / Memory Parity Error.
The System has halted

I rebooted and it happened again. So I decided to Google the problem and ended up here!

Anyone any the wiser yet?

i have the same problem. it seems that it doesn't always caused by memory (http://support.microsoft.com/kb/101272)

after i remove my firewire card, the problem vanished. my computer run perfectly as usual.

fyi, i use hp xw4600 workstation without built in firewire.

Got this error on a Dell D610 after installing a new wifi mini PCI card. Tried replacing all RAM but fault persisted. Replaced the wifi card with another identical type and fault cleared. So it's not always a RAM problem!

I just saw this message for the first time today on my Inspiron 1520 with an 8600M GT. RAM is 4 GB of aftermarket Kingston DDR2, upgraded from Qimonda 2x1 GB stock. Wireless is an aftermarket Intel 5300 ABG Draft N. About a week ago I started noticing that my computer sometimes failed to resume from hibernate, although as I usually walk away while it resumes I hadn't seen an error. Today I saw this error when I attempted to resume from hibernate. Not sure what the error might be yet. Only other odd behaviors recently were many BSODs when playing Call of Duty 4 (which I'd assumed were due to crummy nVIDIA drivers), and a slow wireless connection with XP x64 (works fine with XP x86). But as I'm not at 90%, I'm not too concerned.

Plans if it persists/gets worse:

0). Test with Memtest86+

1). Try switching back to my Dell Wireless 1390 ABG card (skip if Memtest yields errors to 2).

2). Try switching back to my Qimonda 2x1 GB RAM.

3). Call Dell if those don't work? I've still got about 9 months of warranty, so if it's a Bumpgate GeForce, at least I've got recourse.

Just wanted to let you know that I had a Dell E1705 some time ago (about an year ago), I had to sell the laptop as parts because I got the same error as you are getting - memory parity check.

After a lot of testing and diagnostics I can safely say it was the video card memory. A new video card would have cost me an arm and a leg - it was a 7900GS. So I just decided to sell the laptop and get myself a new one.

If you experience this on a Dell with a pre 9000 series nVidia GPU I strongly recommend you use your warranty. The error is often caused by the GPU core breaching and after any warning sign, such as reboots, BSOD, odd colored pixels, lines, and other system problems, the damage is done and it will only get worse. nVidia had been manufacturing GPUs with the flaw since at least 2006. See my post on the previous page. Likely at this point, parts on these older laptops is dwindling and you'll get a newer system as replacement.

Hi,
Thanks All...
I was suffering from this problem on one of my laptop since last 6 months.
This was not my primary machine and hence i could live without it.
The system would work for 5 mins and then go into blue screen and after that,wen restarted,pixels would be forming crude shapes on the screen...

I have the following config

Dell Vostro 1400
Vista
2 GB RAM
nvidia

Tried the following(did not work)
reinstalled vista/xp etc..
replaced the RAM..

What worked...
Uninstall the nvidia dell provided software.
re install the one from nvidia site.


I created this account to thank the people who posted this solution and also to let other people know who have similar config as mine.

Hi everybody I'm a certified dell technician, and I had this memory parity problem with an XPS M1210 while I trying to install a new copy of windows. i've try replacing everything, processor, Mobo, memory, HDD. the only thing that works for me was removing the WLAN card. once I did it the system start to install and the blue screen disappear.

What is the brand and model of the wireless adapter?

first off OMG i cant believe this thread has been going on for over 4 years wow . anyway i work as a pc tech for the dept of ed . i came across this error on a dell 755 desktop , and like most people here this was my first time coming across such an error and there was pretty much no info online about it expect this thread . anyway this unit has on board video VGA and an AGP video card installed , if you boot the unit from the on board VGA it crashes as soon as windows begins to load. so i thought it might be the HDD but if i would boot it into safe mode it would boot all the way to windows and if i removed the AGP video card , the unit would boot fine with no problems , so i figured the video card is the problem , replaced it and everything is ok with it .... i hope this helps someone
