Please help,
Working on a laptop (Dell Latitude E6430 - Windows 7 - Intel Core i5) that always crashes to Stop Error (BSoD) when loading Windows. The error is identified as 'PAGE_FAULT_IN_NONPAGED_AREA' (screenshot attached)
As a preface, the BIOS on this Dell is extremely limited only showing one page with no useful options (screenshot attached) Any clues why this is?
No suggested fixes are working. We tried installing new RAM, which has been tried in both slots, but this did not work.
The Windows Startup Recovery, the System Restore option, the ‘Boot to last known good configuration’ option, all Safe Mode selections and even booting from a Windows 7 Repair disk all result in the BSoD. The Windows Memory Diagnostic finds no errors. I also ran 'chkdsk D: /f /r' in the command prompt, which took about two hours to complete, but it did not find any errors and booting up after resulted again in the BSoD.
If this is of interest, when booting in strict ‘Safe Mode’, as you know, the screen rapidly lists all the drivers being loaded. Every time it stalls on ‘Classpnp.sys’ (D:\Windows\System32\Drivers\) before the BSoD failure. From my research it appears this is a driver having to do with the hard drive, and some forums recommended changing the name in cmd to ‘Classpnp.old’ to avoid crashing. I did this and the driver list did indeed get by Classpnp but then stalled instead on ‘disk.sys’ before crashing. I did not want to mess with this driver name as well so did not pursue the ‘solution’ further. (Classpnp.old has been renamed back to Classpnp.sys) Other forums recommended tightening the hd cables or even removing and then reinserting the hd itself. All this has been attempted with the same BSoD result.
Any suggestions, please help?
