Troubleshoot a specific error/stop message

I got a bsod when my gf was playing an online puzzle game with a specific stop message, is there any way of finding out what this exact code means?
(Memtest gave no errors after letting test 5 and 8 run overnight, paging file is set to 1024mb, min and max value the same and its on a seperate partition, I can game for hours without any issues, it's just when my gf plays these silly online puzzle games, which do not strain my system in any way, that it blue screens occasionally, she saw a Driver IRQ not less or equal error a few days ago but rebooted before I could take the stop message down...)

The exact message is:

Page_Fault_In_NonPaged_Area    0×00000050  (0×BAD0B0AA  0×00000000  0×8054A51A  0×00000000)

Any insights or help would be greatly appreciated!

Some of the links I have found regarding 0x00000050 refer to memory problems, but what you describe sounds like a video card driver problem.  Do you have the latest drivers for your video card?  Or, what make/model of PC and/or video card?  That would be my first approach is to look for video card updates.
And here's a good general page on STOP errors:

Take a look at the following web page,

which is presented using frames.  Click on the error code (50) in the left pane of the page, which is a link to the following quotation:

(Click to consult the online Win XP Resource Kit article, or see Windows 2000 Professional Resource Kit, p. 1548.)
Requested data was not in memory. An invalid system memory address was referenced. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop message, as may other hardware problems (e.g., incorrect SCSI termination or a flawed PCI card).

My drivers are up to date, pc specifications are Opteron 180 on a DFI LanParty Nf4 motherboard, OCZ gamers extreme pc3500 memory and a E-vga 7900GTX GFX card.
GFX drivers were those on the E-vga driver cd, I installed the latest official WHQL Forceware driver of the Nvidia site and see if that helps matters...

The crash may be caused by faulty ram or device driver error (ie video, sound card, modem and etc). The system event log and the minidump has the most useful diagnostic information. When Windows crashes with blue screen, it writes a system event 1001 or 1003 and a minidump to the folder \windows\minidump. Check system event 1001 and 1003 and it has the detail of the blue screen.

Event ID: 1001
Source: Save Dump
The computer has rebooted from a bugcheck.The bugcheck was : 0xc000000a (0xe1270188, 0x00000002, 0x00000000, 0x804032100).
Microsoft Windows..... A dump was saved in: .......

Event Source: System Error
Event Category: (102)
Event ID: 1003
Error code 1000007f, parameter1 0000000d, parameter2 00000000, parameter3 00000000, parameter4 00000000

Control Panel -> Adminstrative Tools -> Event Viewer -> System -> Event 1001/1003. Copy the content and paste it back here

Zip 5 to 6 minidumps to a zip file and attach it at any webspace. I will study the dump and find out the culprit. Make sure that your windows is not infected with spyware, adware adn chkdsk /r.

Get public webspace
Use a free service like rapidshare to attach the minidumps and post the url of the mimidumps at this thread.

Some faulty ram can pass memtest. Reseat the memory module to another memory slot.

OK, thanks, I am going to need some more directions as to how do I navigate to that folder you specified...I searched my Windows folder but didn't find any \minidump folder there.

System event log had only one event with id 1001, and this wasn't on the time of the blue screen, no errors at the exact time of the blue screen, I did make a screenshot of the event id 1001 and will post the link below, my OS is in Dutch so I am not sure if it will be very helpful...

If you would be so kind as to point me to the minidump folder I'll post those asap, thanks again for your help, I really appreciate it!
The minidumps are at the folder \windows\minidump

Is it possible I do not have such a folder?
fdehellAuthor Commented:
Still not sure what caused it but after I installed another videocard driver (from Nvidia instead of E-VGA's driver that came with the card) it seems she can now puzzle without blue screens or stop messages....
I thinks its most fair if I split the points between Expert4XP and cpc2004, too bad I have no minidump folder....
