Sorry, i should have made myself clearer before.
The Wintv re-install was just the point that i initially noticed the issue, and therefore the first thing i test to determine whether the problem has been resolved.
Before coming to you for advice i tried many things. Tdsskiller, Kaspersky online scan, neither would install due to lack of privileges.
SAS won't autoupdate and manual update (by definition download) won't work stating SAS isn't installed.
Even the aswMBR log shows that it failed to initialize properly.
The issue is not wintv only, it is everything. I have no admin privileges whatsoever
One other thing that may be relevant - On desktop during boot i get a window saying 'server busy' with 'switch to' and 'retry' options. This is relatively new, and i have no idea what it relates to.
Hope this helps ...
