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

[nxman]

Dear Khanhfat

I confirm what you said the BSOD is not because of RAM problem
when Lenovo took my notebook I showed them a picture of it
with BSOD visible which I took using my Mobile camera they told me the
picture I took was very helpful and to confirm your theory regarding the ram
they told me that they replaced the ram and they ran PC Doctor and there was nothing and second day they actually decided to send it back to me but before doing that they run WMP 11 for few minutes and the system crashed! BSOD good they saw it themselves!!! They told me they sold more than 1000
T60's with my specs and this is the first time they see this problem and it’s either a defective motherboard or a defective display card which they suspect the most.

UPS didn't come today so I'm still keeping my laptop for next 2 days and wait til Monday if there's anybody come to pick it up.

ShinJi257, is that Gigabyte better than intel. I got an Atheros card from china but it didn't show much improvement. ( Little bit of Off-topic here).

This BSOD is not because of RAM it's something else.

I mostly got an Atheros card because of the linux support. This particular one though supports Super-G networks so it will likely come in handy at some point. I had the Dell 1500 one in there previously which is a Broadcom chipset based one. The network seems to be just as good if not better than the previous one. Then again I am using the same antenna. The a and draft-n support seemed to be overkill so it wasn't that big of a deal to get one that was just b/g.

I ran the full suite of tests in Dell Diagnostics for a Blue Screen in windows and it tested the whole nine yards. Took it a good 4 hours to complete. It came up with nothing. All tests passed. I reseated the memory cards, switched them, and uninstalled i8kfangui. Some forums suggested a possible software conflict can also cause this so I took that one out. If it happens again I will be getting on dell chat.

Update

I received the BSOD on my New replacement T60 while watching vids on mitacafe.com!!! i will stick with this machine even if it gives me the BSOD every minute! hopefully a new Bios update or driver update will fix the problem.

Hello; I've been having the same problems with my Dell 6400 (aka E1505) ever since I bought it in September. The problem always seems to occur when I'm surfing the web using the wireless at home. I went to university in October where I use a wired internet connection and I haven't ever had the error there, even though I use it every day.

After I got home in early December though and started using the wireless again, the problems have started again. It tends to happen at least once a day.

I used contacted Dell and I went through the diagnostics and reseating the memory over the phone. However, a few hours later, the dreaded BSOD appeared again. I emailed the guy I'd been talking to over the phone and asked for a technician. Despite his promise that he'd get one to me the next day, it took over a week for the guy to arrive.

He replaced my RAM, the video card (Radeon Mobility X1400) and the processor. He told me that if it happened again, I should re-install Windows.

Of course, later that day, it did.

I haven't yet done a clean install since I can't face the hassle of backing up all my data and redownloading and installing all the updated drivers again.

It seems like I've tried everything; I've updated the BIOS and I'm on the latest video (and wireless card) drivers from the Dell website.

I go back to university later this week so I doubt I'll be able to sort it all out before then or before the end of term. I'm very paranoid that it's going to crash mid-essay.

Welcome Harry1W

its because of Radeon Mobility X1400 but untill now no resolution to this problem.

[Harry1W]

OK then; am I right to surmise that this issue has arisen as a result of incompatibility between the video and the system setup? I'd see it very unlikely that is something inherently wrong with the hardware itself alone, given that the replacement of the X1400 didn't help to solve the problem.

Do you think that a clean install of Windows, therefore, is the only option - at least until Dell/ATI pull their fingers out to get a driver fix? I wouldn't want to reinstall just to find that the problem reoccurs though!

Could it be connected to the wireless adapter - possibly an incompatibility with the X1400? I'm just clutching at straws - but the incidence of the problem does seem uncanilly correlated with the use of wireless broadband. I seem to remember reading earlier on this thread someone else mentioning that the problem seemed to occur when they were using the Internet; I don't think it's ever happened to me when I've been using the laptop with the wireless turned off.

reinstalling windows didnt fix the problem for me. currently dell has replaced 3 of my hard drive. my orginal drive failed the dell diagnostic test somehow, when i pass the exact same test 4 hours previous to that 2nd test, the 2nd hard drive has weird clicking noise so dell sent me a new a hard drive but it was IDE and not SATA so i had them send me another one. i am still getting those NMI errors though.

i have also played around with the ram, i had the laptop run on 1 stick 512 mb of ram and swapped them when i encountered a NMI error and it still occurred. these are the default dell ram.

i ended up sending the laptop to the dell depot and the blockheads over there basically returned the laptop to me untouched. they claim that there was something wrong with the hard drive but they did not have the one that i needed at the depot so they would send the hard drive in a day from somewhere else (this is where they ended up sending the IDE hard drive instead of SATA).

the whole process is seriously pissing me off. not only did they literally returned the laptop without replacing a single thing, the person who packed my laptop in to return literally just threw it in the box. when the laptop was returned to me, one of the plastic grid thingy for the fan in the back was broken and for some reason 4 of my keys on the keyboard were broken (they were working fine before i sent it in, i use end/home/pg up/down a lot) . so yea they basically returned my laptop untouched and ended breaking a bunch of crap as well.

so yea i had to spend another hour on the phone with dell to get a new keyboard and they are basically doing nothing about the damage done to the plastic thing they broke. college starts for me again on january 20th so i don't have much time left to send the laptop back and forth anymore.

I don't have time to send that laptop back and forth either. My college starts on 16th...

I sent to the repair depot last week and they didn't change anything. They just boot up the Windows and run their diagnosis test.. but this error can't be determine BY RUN THE DIAGNOSIS SOFTWARE TO TEST THE HARDWARE.

It's only happend when you actually using the windows and work with it. If it's the ATI drivers, Has anyone try to run windows with NO ATI drivers?

All of the story I've read above and all the testing that Dell suggested me , I've been through them all. If you can't stand it no longer... just return it and get some other laptop and use it. I wonder if this issue affect on all inspiron or 50% of them. I doubt that there're many E1705 1505 out there has the same problem , which would drive the owner nuts.

OK... so I stumbled across your forum thread while trying to figure out what the problem is that I kept getting. I have a fully loaded thinkpad T60p that I got for graduation about 8 months ago. Up until now it has been working like a charm. I decided to upgrade it by buying another gig stick of RAM. First I tried PNY. However, after about 10 minutes of wonderful speed and gaming it would crash my computer in various ways. I figured, hey its probably a bad stick.. got a refund.. and this time I mail ordered some nice Corsair.

So, I install the Corsair today and My laptop runs very smoothely for about an hour. Then while running an online game, I had that awful blue screen with the "NMI: Parity Check blah blah" error. I restarted.. and pretty much every 20 minutes it kept doing that. Well.. I decided to test my new ram by switching it out default stick. The only RAM my laptop had at that point was my new stuff. It ran fine for about 2 hours. So i stuck in the default stick in the 2nd slot this time.. and it ran for about 30 minutes and gave me that dang error again.

Is it possible that my 2nd RAM slot is faulty? or do you think it is an ATI/ PCI bus error? (which seems to be the general consensus). I am quickly running out of ideas of how to resolve this. I really want my 2nd gig of RAM!

im not sure if the ati drivers are to blame, i have the nvidia 7900 gs and its there too.
