I have a AOA 150-1570 win XP 120gb hd 1gb ram and BIOS 3305 I had to use the ALT-F10 erecovery tool and everything was working fine up untill it was all finished loading up and then it goes into a rebooting cycle so I hit F8 and selected that it dosent reboot when it terminates and I got to read this message on a blue screen! STOP: c000021a {Fatal System Error} The windows Logon Process system process terminated unexpectedly with a status of 0xc0000005 (0x00000000 0x00000000). the system has been shut down. Its like a dream. The guy on the phone didnt seem to be very interested in troubleshooting this and just told me I would have to purchase some CD's Help anyone?
