Blue Screen of Death in Hardware Hangout Posted February 8, 2008 · Edited February 8, 2008 by bluescreens It's a RAM problem!I definitely agree. Also, you can get that main stop error code (PAGE_FAULT_IN_NON_PAGED_AREA) if you installed incompatible RAM or have a bad RAM slot. Gotten that error code before after installing another 128 MB PC133 SDRAM module to an IBM PC300 GL. (Pentium III Katmai 533 Mhz with 133 MHz FSB)Surprised me, because the RAM module was fine with a couple of Via KT133 based motherboards.Here's what MS says about their error:CauseBug check 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).Another common cause is the installation of a faulty system service.Antivirus software can also trigger this error, as can a corrupted NTFS volume.EDIT: Ooops - didn't recall that I'd already debugged this. This is an ATI card issue. Not a RAM issue. The dump was debugged, the user switched to another card, and the problem is resolved. Best path forward when you see a blue screen of death: debug the dump.
