Bsod page_fault_in_nonpaged_area

Do you have any other PC shops around? I would suspect the video card first of all, but if you can get a better PSU, that would also be great.

I have already searched in other PC SHops but they are all not willing to give me any stand by products..even to test..they all recommend to buy a new card and psu..i will give some details..when I sent a mail to CoolerMaster they told to replace the PSU since this 350W PSU is 12v current rating of 10A.But in card's minimum requirement it is written that it needs minimum 350W with 12v current rating of 18A when configured with a CORE 2 DUO setup.I am using Core 2 Duo.During normal time without verifier,the card is still working but not upto its potential?During booting,all components operate at its maximum speed am i right?so when driver verifier is enabled,it triggers a bsod due to misbehaving driver that is graphics card?This is just my assumption.
Another thing is thaT GT 240 1GB DDR5 is still faster than HD 4670 right?since GT 240 has a memory bandwidth of 54.4GB per sec while HD 4670 has 35.2GB per sec.My friend is using HD 4670 and he gets a score of 6.7 in WEI (graphics for Aero and gaming graphics).I get the same score.Thats means the card is still not working upto it's potential am i right?

Have you tried disabling Aero and graphics effects? See here: Visual Effects Settings - Change

Select "Adjust for best performance".

I took processor,ram,graphics card and hard disk from this system and put all that to my friend's computer.First of all,before using all these components to her system,I uninstalled the onboard graphics driver which was installed and put the graphics card and installed forceware drivers and enabled verifier.BSOD occurred and I removed the driver and card from the system.Her power supply unit is 450W and providing enough power to card.Now this time,I installed onboard card using Windows driver and enabled verifier.Since she is using the same board,processor and ram,I just decided to check.It was unexpected.BSOD occurred.I became confused and her system has too the same problem.Then I contacted Intel Technical Support and told this strange issue with DG41WV boards.He told it's actually because we are using 1333Mhz RAM and when it is used in these boards,it will down clock to 1066mhz due to chipset limitation.In Windows 7,driver verifier has an idea about overclocked / downclocked ram and that's why it detects an error.Thats why the error is not detected in Windows Vista and XP.It is actually due to downclocked RAM.He told there is nothing to worry about this downclocked RAM and is normal.I asked him about yahoo messenger and he told that BSOD occurs during gaming only if yahoo messenger is in the background.But no bsod occurs if it is another program.So the issue is with yahoo messenger due to Script errors.I don't understand what he told about that.But I understood that it is a yahoo messenger issue and not the system.Finally he told that our system is working normally.Disable verifier for better stability.
So what now?Do you think he is right?Looks like my system is normal :)

The strange thing is, Driver Verifier is not a hardware diagnostic. It tests software, not hardware; the increased system resource usage may be what is really triggering these BSODs.

That being the case, disabling driver verifier will most likely slow down the BSODs; I doubt it will stop them completely however.

Ok..So it is still unknown what is causing the BSOD when I enable verifier in Windows 7.Is there any difference in verifier of Windows XP,Vista and 7?
I used XP SP3 and enabled verifier.No bsod..worked perfectly even with verifier enabled.For Vista too.I used Vista SP2 and enabled verifier.Still worked perfectly.But in Windows 7,i am getting the issue.The main problem that bsod while gaming with yahoo messenger is a software issue I think,since nowadays I use web yahoo messenger (using web browser,IE) and play games.No bsod.Still works fine.
Can verifier make mistakes?According to that Intel Technical agent,the only problem not a problem actually but cause instability for ram as well as chipset since RAM has a native frequency of 1333mhz while due to chipset limitation ,it is downclocked to 1066mhz..and when I asked about this ram manufacturer Kingston,they told the same.It is not advisable to use the ram with this board..

As long as the RAM meets the minimum speed requirement (the speed of your motherboard), it should be fine. RAM faster than the speed of the motherboard is fine to use.

ok..Is there any differences in verifier of XP,Vista and 7?
