I have an HP Pavilion laptop running windows XP, two weeks ago the power supply jack broke and was repaired. When I picked up the machine we powered it up both with the battery and the power cord, everything was fine. When I got the maching home and powered up I got the message LSASS.exe - system error, object name not found, then it immediately rebooted and that was all the further I could ever get. Since I don't know much about the working of computers I had someone that does looking/working on it. He has changed the hard drive, rotated the memory, ran a memory test for 95 hours and a scan disk on the hard drive. All of that was ok. Now he is getting the error IRQL_NOT_LESS_OR_EQUAL, 0x0________A, oxo_______0,8, oxo_______2, oxo______o, 0x804ec057. Any suggestions.
