recently I had this BSOD when playing an online game : Code: Event Type: Information Event Source: Save Dump Event Category: None Event ID: 1001 Description: The computer has rebooted from a bugcheck. The bugcheck was: 0x00000050 (0xb91990ea, 0x00000000, 0xb91990ea, 0x00000000). A dump was saved in: C:\WINDOWS\MEMORY.DMP. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. I already tried using memtest to check my memory, but it passed the test with no errors. Also tried changing my nvidia driver to older/newer ones. using XP Pro SP2. Minidump file also included.
