I upgraded my cpu recently to a Q9400 Quad core cpu on a EVGA i680 SLI motherboard. I have Vista Ultimate x64 running on it with 2 TV tuners from ATI the ATI TV Wonder 600 and an internal digital card. Everything worked fine prior to the cpu upgrade. After the cpu upgrade (and firmware update to the motherboard). The Media Center crashes and does not recognize the TV tuners (although they apparently installed with no issues) and the Media Player also crashes if I try to do or play anything in it once opened. I have provided the following problem reports for the different crashes that i have seen. (FYI - I also have been running iTunes prior and after the crashes with no issues):
