Processor upgrade causes media error messages for Tuner in Vista U

I have upgraded my processor and now get error message.

"digital cable device registration application stopped working and was
closed" I cannot now use my Tuner.

If I put back in my old processor it goes away and |Tuner works. If I put in
an earlier processor I had before windows Vista Ultimate upgrade I get same
message.

I seems only the processor i upgraded Vista with works. CAn any one help.

What's the fault bucket data for that crash according to the Problem Reports
and Solutions Center control panel:
