It's actually getting a BSOD some 10-20 seconds after showing the desktop. Who Crashed reports all the dumps in the PC show a Registry Error.
I've checked the HDD - no fault found - so, suspecting a possible corrupt User Profile I've created a new user using my name and and booted into that. It's working fine and I'm currently running an AV scan.
It would seem therefore that the original user profile is corrupt in some way. My current plan is to create a new user for the sister and, using the temporary user I have copy the files from original user to new user.
Is this a sensible approach?
Will it mean that, albeit under a new user, everything should work much the same. There are no fancy apps running on the PC, MS Works seems to be the main one used.
Possibly a daft question - what can cause a corrupt user profile?
We have more and more laws, and less and less enforcement
