I'm sorry to say but a reinstall is probably the best way to return your system to a stable point. You've made a number of changes, one on top of the other which makes it tricky to diagnose these types of problems. Additionally RU2 works much better when applied to a clean install. Because you've applied it to a damaged installation, I really doubt you're going to get much joy.
However there is one last roll of the dice.
- Try rolling back the Dvico driver to the version that was working for you and then run the MCE reset tool details that can be found
here. You may have some luck. I really do recommend a rebuild and using a drive imaging tool along the way so if something like this happens again you can roll back to a known working image.
Cheers
Matt.
