Stop 0x00000050 or PAGE_FAULT_IN_NONPAGED_AREA

Win XP Home

System keeps crashing with BSD and error Stop 0x00000050 or PAGE_FAULT_IN_NONPAGED_AREA

Have tried removing all but the necessary parts for sys to boot - tried swapping Ram and even hard drive. But same error keeps happening - reading on the net that usually related to defective RAM, be it main memory, L2 RAM cache, or video RAM have removed grphics card and tried different ram. Still same fault - this leaves L2 Ram as possible cause.
Is there a way to a) test it and/or b) replace it - or is it time to replace mobo or even whole PC?

As always any help and suggestions gratefully received.

Faulty hardware. Stop 0x50 usually occurs after the installation of faulty hardware or in the event of failure of installed hardware (usually related to defective RAM, be it main memory, L2 RAM cache, or video RAM). If hardware has been added to the system recently, remove it to see if the error recurs. If existing hardware has failed, remove or replace the faulty component. You need to run hardware diagnostics supplied by the system manufacturer. For details on these procedures, see the owners manual for your computer.

I know it says 2000, but it still applies.

Some other ideas depending on what you were doing.

Having tried another hard drive the system crashed when it was installing XP - so think that rules out a driver issue. Also had one stick of ram in - this is what leads me to think it is the L2 Ram cache.
I am guessing this would mean a new mobo?

Disable L2 in the BIOS if you can. I have used mobos where I could, but not many will let you.

Test again.

Thanks Train will try that in the morning,

Will let you know how it goes

Do let us know.
And post the make and model of the computer or the same for the mobo if it is a custom/home built one.

Hi

Couldnt find option in AMI bios to turn off L2 cache

PC is a Packard Bell UTOW? - about 3years old

Mobo is a ASUS P5S800 VM with an Intel Celeron D 2.93Ghz CPU

As the L2 cache is built into CPU may try changing that to see if that is the problem

Any further suggestions welcome

Guess ing , but try a BIOS update if available.
Maybe the cpu is damaged??
Mobo going bad.

One or all of those is what I see as possible problem areas.
Hope someone posts somthing I have missed that works.
