Where did you get your patches ?
MS update ? [When online click tools / windows update]

What other tools do you have installed - updated - and USE .......

Did you upgrade to XP, or dual boot ?

If you want to start afresh on two HDD's.
start with ONE .......
save data to a cleared area on 2.
reverse for second drive.
SP2 is on MS's update site too [75MB]
