Hey, I have had the same problem happen as some users in this thread. I had a power outtage one night and awoke to this BSOD:
STOP: C0000218 Registry File Failure
This registry cannot load the hive (file):
\SystemRoot\System32\Config\SOFTWARE
I found a thread where someone gave detailed instructions on how to fix this. I followed them to a point. Here is the link to the Solution I used that gave me the Fatal Error:
http://www.kellys-korner-xp.com/xp_sys32.htm
When I turned the comp back on I got a different fatal error, the one that is in this thread:
C000021a {Fatal System Error}
Blah blah
f 0xc0000135 (0x00000000 0x00000000)
I then did some research for a resolution for this error code and decided to uninstall SP3 via recovery console. I followed the directions on this link here:
http://www.computing.net/answers/windows-xp/unins...onsole/169701.html
When my computer started back up I successfully logged into windows only to find that half of my desktop items were missing, I had a default theme and background, and many drivers didn't load (mouse, ect.) My documents and everything isn't in plain sight, I have to dig deep in the C: to find them. How do I fix this? What did I do wrong? I am still running SP3 too. I followed the bottom steps on the uninstalling SP3 link as well (going into the registry and changing the Value data in RcpSs ObjectName to LocalSystem and this changed nothing).
Please give some help I haven't had my computer running in about a week!
