Hi,
I was directed over here by someone in the Leaky reading group who said you may be able to help/explain with my problem.

At the beginning of the month I got a brand new Acer Gemstone Blue (6920G) laptop.
It was fine the first time I put it on,and lasted a good couple of hours.Now though it lasts about 5 minutes before the screen goes blue and comes up with the message..... **Hardware Malfunction** **NMI: Parity Check....Parity Memory Error** **System Halted**
And the last time I tried turning it on it froze at the welcome page. sad.gif

I have no idea what it means.I've emailed Acer,but have yet to get a response.I was wondering if any of you guys could help me.

Thanks!

It says Hardware, so that means it's not a virus problem, I wouldn't think-- although you could on startup go to advanced boot-up options and go into safe mode and run some virus tests.

My only other advice on that would be to bring it to Acer(?) or wherever you bought it and let them look at it. Or a computer company like The Geek Squad could probably help, although probably an expensive alternative.

Not really sure, sorry sad.gif

Parity check errors are USUALLY a problem in the CPU where a calculation is done to check the state of the cpu and the wrong answer is given. It is either a manufacturing fault, or a heating issue; like a loose heat sink on a CPU. In this case changing OS will not help you regardless of how cool Linux is.

I had this problem on my PC when i upgraded the motherboard and one of the connectors holding the cooling unit to the CPU wasn't connected correctly and it took me ages to figure it out. I nearly threw away the PC. Once that was fixed, however, the problem went away and I'm as happy as a clam.

Since the pc is still new, it should be under warranty and I would take it back to the retailer where you bought it from for either a) a repair or b) a replacement if I were you.

What could be the case though, although way less frequent, is a driver issue between the motherboard and the OS - which would be hard to fix anyway if you cant get past the POST (pre startup checks)

Either way - its new: its best to take it back and get it sorted out by the manufacturer.

Excellent diagnosis, Dr. House Hagrid!

Keep in mind that many hardware errors are thrown by the BIOS, which is independent of the operating system that is running, and so changing one's operating system isn't necessarily going to fix anything.

Also keep in mind that Linux and Mac are by no means virus-free. My Windows is virus-free, for instance--is that because it's a distribution of Windows? No, it's because it's properly configured and protected. See these examples of when good OSes go bad. I'm not intending to derail the subject of this thread to discuss this--I'm just trying to widen people's perceptions.

Based on the symptoms, there is a couple of possibillities:

1) As Rudius mentioned, this could be a problem with CPU/chipset
2) As Crazy mentioned - this could be a malware infection
3) IMHO this is the memory that is foul: First, the error message indicates that the parity check of the memory is shot - secondly the system doesent manage to boot at all...
It could be as simple, as the memory card isn't set securely in the slot.

May i humbly suggest: use a Ubuntu or Knoppix live-CD to check the memory/hardware: under boot options, there is a 'memory check' option - run that one. I have set a 'troubleshooting tree' up here - if you follow the sequence, you should be able to pin it down:

If Ubuntu fails to boot then hardware fault do return the device to seller for repair
If Ubuntu boots, but fail memory check then memory fault do return the device to seller for repair
If Ubuntu boots, and passes memory check then software fault do malware scan
If malware scan fails then remove malware... and probably return to seller to re-install your OS all over again. (Concider keep using Ubuntu.)
If malware scan passes then return to seller for reinstallation of software... (or keep running Ubuntu! smile.gif Yes, i know... i'm partial to that stuff...)

I hope this is clear, even though written in 'pig BASIC'. I guess, as your machine is still under warranty, you better bring it in, no matter what. If you open the box, you void the warranty.

------

Nick may i be allowed to disagree slightly?
'Bliss' is one of the very few vira ever found for Linux: the grand total is - to the best of my knowledge - five. There is about 15 - 20 theoretical possibillities, none ever found 'in the open'.
You can still claim that it's damn close to impossible penetrating a Linux system: the five functioning vira has all been for 2.2 kernels or older (now we run 2.6.whatever), and every single 'possible' is rendered harmless - if you keep your system updated.
After over 10 years of running Linux, i have - so far - never found a single infected machine, nor talked with anybody that had one.

Just for comparision: McAfee's malware scanner for XP has to check for over 80.000 vira, worms and variations over these. And each and every one bites. Your strategy of keeping your box up-to-date at all times, is indeed a wise one.

OK to prevent TWO threads discussing computer security feel free to continue the virus discussion here whereas this discussion will remain on troubleshooting the PC.

Just in case you haven't, it's also great to do a bit of googling about it:

Other forums have threads that may be useful.

Thank you all so much for your suggestions!

I tried turning it on again today to get on the Unbuntu website and try that,but I had to do a scan first as it said it hasn't had a full system scan yet and I wasn't protected.
It got half way through and went to the error message again,so I didn't even manage to get online. sad.gif
I turned it off then on again,restarted the scan and then the screen started flashing.It rebooted itself but then it happened again soon after,(flashing screen which then started pixalating and wouldn't stop.)

I don't know whether it has anything to do with the video driver as it only started to go wrong after I watched the new HP trailer online,the day after I got it.

As I know absolutely nothing about the inside workings of a computer,I think it would be best if I took it to Currys (bought it from them online) for them to have a look.If I started taking things out and moving them around I know for sure nothing would end up in the right place!
Being under warrenty I wouldn't have to pay,would I? (knows nothing about these things huh.gif )
