Hello, I'm trying to fix my sisters Dell Latitude D610 laptop, which blue screened more than a week, but less than a two weeks ago. It seems like anything could generate this error message. The original phone call/complaint was that she lost her wireless connection. I checked the device manager, there where two exclamations under pcmcia adapters and no wireless card was listed under network adapters. I then uninstalled the exclamations and scanned for hardware changes, it found the wireless card (no exclamations) and I clicked to reboot. It booted perfectly, I entered the encryption key for the wireless and the laptop froze while I was waiting for the confirmation. I rebooted and got the page_fault_in_nonpaged_area error. I called my sister back, figuring I didn't get the whole story... The first sign of a problem was the laptop freezing during bootup, while the animated windows progress bar was showing. She said this happened 4-5 times before she called yesterday, when she lost the wireless connection and had to use the desktop computer. I then tried a system restore and rolled back to July 1st, and still got the blue screen. Thanks in advance.
