PC crashes

[ppppenguin]

I can recover my bookmarks from elsewhere easily enough. Not quite up to date but good enogh. I think that the real problem is that the user profile folders are now badly mucked up so heaven knows what else will be broken. I'm on the verge of doing a clean install of W7 and all my software. My data is all backed up (it's all on the physically separate D drive and not in the user folder except for some very minor bits)

Anything to watch out for as I'm doing the install? Would be nice to cure the crashes at the same time.
