Hi all Not sure if this has been discussed here but installing SP2 trashed my PC! After installing SP2, the PC said to restart to finish the process, but then on restart refused to boot! I have spent a week 'googling', searching, rebuilding, trying, retrying, to get it fixed. Microsoft warns that this can happen on Intel 'Prescott' chips on certain motherboards (not well publicised) but I have an Athlon chip! XP refused to 'Repair Install' when booted from the CD as it couldn't recognise the original Installation, so would only put in a new installation deleting my old data. Recovery Console refused to work without a password (I have never set one!) Removing the Hd and putting it in a different PC got me my data back, and eventually by transferring over data from the 'Repair' folder to the windows system32 folder I eventually got XP to recognise my old install and do a repair install. However, the user names had disappeared on reboot and I couldn't log on as anyone! With safe mode I overcame this, but then found that the modem was unrecognised and couldn't be used. Modem options were 'greyed' out! I had to edit the registry to repair this fault, then edit the BIOS to get the non-working USB ports going again. The floppy disc icon disappeared from my computer and although I got this back by editing the BIOS again, it still refuses to work - insisting that I insert a disc even when I have done so. Searching through Google shows the Floppy problem to be a common one (even without SP2) but with no known solution. Anyway - Please be warned, SP2 works well on many PCs' but trashes some. It has wasted a week of my life and reduced my PC's capability. I now really understand why so many people detest Microsoft so much.... You've been warned - don't install SP2!
