Hi, this is my first post, and unfortunately this is concerning the stop error my computer has been experiencing. The computer I've been using was fine until I've installed the Windows updates that are automatically downloaded to your computer. After the installation and subsequent reboot, the computer always crashes with the following stop error: Page Fault in Nonpaged Area Stop: 0x00000050 (0xFFFF00F8, 0x00000000, 0x80543C1D, 0x00000000) The Windows XP boots up to the log in screen; when I log in, the crash always happens as the OS seems to initialize services and start up programs. I've tried the Safe Mode, and I can log into the 'Administrator' account whereas I cannot log in using the normal account. I can only log in without problem if I opt for Safe Mode with Command Prompt. I've tested the memory (1GB total, 2 sticks) without problems following the outline in the welcome thread. I've tested each single stick individually, then together for around 11 passes without registering a single error. Chkdsk also ran without detecting any problem. I posted a zip of six minidump files as attachment. Thanks in advance for giving me some tips to resolve the problem. If there is anything I can provide such as hardware info, please tell me. Thanks again.
