Every time my Windows starts I receive a blue screen stop error with the following technical details: PAGE_FAULT_IN_NONPAGED_AREA STOP: 0x00000050 (0xE136B000, 0x00000000, 0x80535F5C, 0x00000001) After finishing dumping memory, system restarts. I have Windows XP Pro SP2 installed with IE7. I also attached 3 zip files containing dmp files in "C:\WINDOWS\Minidump" for reference. Is there any way to figure out which hardware or software causes this problem from the STOP error codes or dmp files in order to fix this annoying problem? Please let me know the solution. Thank you very much.
