I don't know if you can help regarding the following problem but, if you Can, I really need your help. Because my PC used to operate with ME and was updated to XP Home, my filing System was FAT 32. Due to the fact that NTFS is a better system, I decided To convert from FAT 32 to NTFS using the XP built-in converter. All went Well except for one major problem...after startup and after approx. 3 to 5 Minutes, a blue screen appears that reads: "a problem has been detected and Windows has been shut down to prevent damage to your computer BAD_POOL_HEADER" then the message goes on telling you lots more regarding Uninstalling any recent programs etc. (there has been no real recent Programs and naturally this error is caused by something to do with the Conversion). I tried rebooting many times and the same problem keeps happening. After Approx 5-7 minutes it reverts to the same blue screen message in ALL Circumstances..I.e.. If I log on as normal or if I don't log on and don't do anything. NOTE 1: someone suggested the following but it did not help "Switch off Microsoft's indexing service. You can do this by clicking the start button, select "Run", then type "msconfig", then select the "Services" TAB, Scroll down to the Indexing Service and Switch it off. Reboot your computer, and good luck - maybe it will work" NOTE 2: for some reason I am not able to get into Safe Mode now. Any suggestion on how to do that other than the usual way? If you can help solve this problem it would be very, very much appreciated. Needless to say, I am able to write to you because I am using my wife's Computer. Thank you for your time!
