Windows XP BSoD help needed

OK, I keep getting a "Page Fault in Non Paged Area" BSoD at random times, but quite often, i.e. 5 or 6 times a day. I know that this is usually an error with hardware/drivers, or with RAM.

This is a new system I built, with all new parts, and Ive already taken Norton off, which i know can cause this error. Other than that, there is no other software that i think would be causeing the problem... Firefox and Nero and aim is about everything installed so far.

I have updated windows with everything available except for SP2.

What I need to know is if anyone knows another cause for this problem, or if I just need to return the RAM and get a new stick. Im trying to avoid that if possible, cause it was bought online, and not from Crucial, so it can be a pain in the ***. Also, I have two sticks in there, a new 512 generic stick that i just ordered new, and an old 256 stick i had layin around the house.


Any help is appreciated.

 

Download Memtest86 onto a bootable CD or floppy. Reboot the computer with the CD/floppy in the drive. Run Memtest86 to find out if the RAM is bad.

BTW, buying generic RAM is usually a bad idea -- always go with a brand recommended by the motherboard manufacturer. If they do not recommend a brand, I personally use Crucial, Corsair or Kingston.
