Hi, this seems to be the place where people actually know how to do something w/ minidumps. Dell Latitude D800. Dell has replaced motherboard, wireless card and windows has been reinstalled several times. Machine reboots randomly generally weekly then gives error info on startup: BCCode=1000000a BCP1=0551001A BCP2=000000FF BCP3=00000000 BCP4=804F29F2 Minidumps included. Thanks for any help!
