I am still not sure what had happened, but there is a good chance it had to do with SP2 updates. My computer will not boot into windows and it won't boot from cd in Bios. I have tried different orders in the BOOT bios such as: 1. cd-rom 2. Hard drive 3. disabled 4. disabled and also with the 2nd and 3rd slots disabled and 4th as HD. When the computer crashed it had a message about "Lsass.exe could not locate component" Thanx for any help.
