I got a looping BSOD the other day. This was resolved by pressing F8 and selecting last known good configuration. I attach some error reports from the event viewer and am trying to decipher what it could be. Any ideas? Thecomputer has rebooted from a bugcheck. The bugcheck was: 0x0000003b (0x00000000c0000420, 0xfffff800030292da,0xfffff880038c10e0, 0x0000000000000000). A dump was saved in:C:\Windows\MEMORY.DMP.
