I have a Compaq Presario v6000 with Windows XP pro SP3. Yesterday I restarted after windows had completed an automatic update. While it was booting up it gave me a message that windows failed to start properly. I had the option to boot up in safe mode, use the last known working configuration, or boot up normally. I tried starting up in safe mode, but it would freeze as it was loading up the drivers. Using either last known working configuration or booting up normally resulted in a BSOD, and it returned me to the failed to start screen. I checked my HD and the RAM, and both cleared. When I went home I managed to recover windows using my recovery CDs. I'm back on SP2 instead of SP3. My question is, what happened and will it happen again if I update windows? Before all this happened, I kept getting random BSODs saying there was a problem with rbdss.sys.
