BSOD - Page Fault in Non Paged Area

Hi, I have a laptop (HP 6735s) which is currently running XP (downgrade from Vista - used HP Disks) and when ever i turn the laptop on it BSOD's. it's fine after a restart but if its turned off and turned back on again, it BSOD's and it's always the same error. Page_Fault_In_Non_Paged_Area Tech Info: ***STOP: 0x00000050 (0x80097000, 0x00000000, 0x8053A6B3, 0x00000000) Cheers for any help Duey

Hi Duey.

Typically when there are blue screens without any clear reason it is beneficial to eliminate the obvious potential problems. Those would be hardware trouble, or malware.

The first tests to run would be a check of your memory using something like Windows Memory Diagnostic, and then performing a check of your hard drive using the chkdsk /r command.

Once your system has passed some basic hardware tests then you can address the issue of possible malware. Do you maintain active and up to date malware protection? Have you had any recent warnings of infection? Have you had to remove any malware recently?

A part from that answering when this problem started occuring, what changes might have been made around that time, etc. would help. I am curious, when did the problem start happening in reference to the initial installation of Windows XP?

If it is not a hardware, or malware problem then it is most likely a driver issue.

i can safetly say that there is no malware present. the operating had been reinstalled on wednesday afternoon and on thursday morning, it was BSOD'ing on every second start-up. i googled the Page_Fault_In_Non_Paged_Area error and found a microsoft page that suggested, among other things, to run chkdsk /f /r. I reinstalled the laptop, installed all drivers, turned it off overnight and in the morning, it was BSOD'ing. running chkdsk /f /r seems to have fixed it but i haven't had much time to test to confirm / deny wether that is the case. Cheers Appleoddity

Hi Duey. Let us know if the problem is resolved. I do offer further concern that the chkdsk /r (the /f is not needed if you use the /r) fixing your problem can be indicative of further issues with your computer. Namely bad sectors on your hard drive can be a sign the drive is failing or having some problems. More sophisticated tests on the drive might be beneficial. Many newer HP/Compaq laptops like yours have a hard drive test in the BIOS you can use. It would be my suggestion that you get into your BIOS setup (F10 or F2 during initial power on tests, i believe) and then look for the hard drive test. Run it and make sure it certifies your drive is OK.

Hi appleoddity, the issue is still unresolved. i've just run the inbuilt hard disk test and it has passed all three phases of it. it still only does it on every second start up

This is a fault in the display adpater driver.

Go into safe mode

In the message that states that Windows is running in Safe mode, click Yes.

Click Start, click Run, type msinfo32 in the Open box, and then click OK.

Under System Summary, expand Components, and then click Display.

In the right pane, note the information that corresponds to the INF File item, for example, Nv4.inf, Oem0.inf, or Atim128.inf.

Quit the System Information utility.

Click Start, right-click My Computer, and then click Properties.

Click the Hardware tab, and then click Device Manager.

Expand Display adapters, right-click the display adapter, and then click Uninstall.

Click OK.

Click Start, click Run, type cmd, and then click OK.

In the Command Prompt window, type the following commands, and then press ENTER after each line: *insert file names from before, below*
ren %systemroot%\inf\INF file name from before.inf *inf.old
ren %systemroot%\inf\INF file name from before.pnf *pnf.old

Close all open windows, and then restart the computer in the typical manner.

Log on to Windows by using an account that has administrative privileges, and then wait for Windows to detect new hardware.

When the Found New Hardware Wizard starts, click Cancel.

If you receive a stop error after you remove the updated display drivers, restart the computer and use the Last Known Good Configuration option. To do this, restart the computer, and then press the F8 key while the computer starts. On the Windows Advanced Options Menu that appears, use the ARROW keys to select Last Known Good Configuration, and then press ENTER.

If you receive a "System Has Recovered from a Serious Error" message when Windows starts, restart the computer again. This error message does not recur.

Obtain and install the latest drivers for your display adapter.

Let me know if that worked

Good Luck

HI Duey. You can try reinstalling or updating your video drivers as suggested above by downloading them here: http://h20000.www2.hp.com/bizsupport/TechS…Item=ob-66449-1

However, if that doesn't work, please attach a few minidumps from the blue screens you are getting.

Minidumps are located in the C:\Windows\Minidump folder. Sort by date modified and find the most recent 2 or 3 minidumps. Please hold the ctrl key and select each one. Once you have them selected, right click one of them and click send to -> compressed zip folder. This will create a new .zip file containing those files which you can upload and attach to the forum for me to take a look at.

Take care.

thanks for your replies i'll have a go through them in order now and let you know tomorrow how i got on. Cheers

Pcs365, rather than copying a large post like that and then not providing proper attribution, please just post a link to the web article. It's actually easier and that way there is no plagiarism involved.

I found the same info you posted here: http://support.microsoft.com/?kbid=329293

I'm not trying to discourage you, please continue to respond to posts. Just be up front about where your data comes from when it's meaningful to do so.

very quick update: i'm at the "Obtain and install the latest drivers for your display adapter." step. the driver is 502MB and over company wireless, this can take a while sorry, wrong download window! it's 97.8MB

NEW driver = Same old problem Minidumps don't exist i've been into the C:\windows folder and there's no minidump folder (even with hidden folders shown) I've also had a look in System Properties, Advanced, Startup And Recovery and under the "Small Dump Directory" it points to %systemroot%\minidump i ran that command and it can't find the folder? Really starting to annoy me now this is!

Hi Duey. Thanks for your diligence. Although, the link I provided you from HP is the link to the most current drivers that they offer for your video card. ATI may have more recent drivers available direct from their website, but the drivers provided by HP are only 98Mb. I'm not sure where you are getting 500Mb from? Possibly you may have installed some incorrect drivers on your system?

Like I said previously, this problem most likely is a driver issue if hardware has been eliminated as a culprit. Lets take a closer look at some stuff.

Can you please run a PCPitStop test so I can see what is currently installed on your system? Thanks.

How to run PCPitStop's Overdrive tests:

• Please click here to go to the PCPitStop Overdrive sign-up page: Signup at PCPitStop (You need to use Internet Explorer with this test so that an ActiveX control can be installed.)
• Click "Create a free account"
• Enter in your relevant information on the sign-up page. You must sign-up in order to have your results recorded so that we can take a look at them here.

i got 500MB as i was downloading office 07 Home user and the driver at the same time in 2 different windows and took the size from the wrong window. i've also eliminated RAM being a problem by testing each stick individually and on all ports available and the problem still persisits. i'll run the PC Pit Stop test now. Thanks for the assistance so far Also, i've got no A/V installed and haven't done really ANY updates. this is because it's only a new install.

I appreciate your hard work. Eliminating the hard drive and memory was a good thing to do even if you weren't having these problems. Its good to test these things occasionally. We just want to get a better view of your system in general, so the PCPItStop test will help. Thanks.

here you go
